StatCalc: Statistical Calculators 14. Command Reference 15. Saving Lives, Protecting People It enables physicians, epidemiologists, and other public health and medical officials to rapidly develop a questionnaire or form, customize the data entry process, and enter and analyze data. The Form Designer module allows you to place prompts and data entry fields on one or more pages of a form. Since this process also defines the database(s) that are created, Form Designer can be regarded as the database design environment. The Check Code editor within Form Designer customizes data entry providing many commands and functions. It enables operators to validate data as they are entered, auto-calculate fields, provide skip patterns, and deliver messages to the data entry user. For more information, see Introduction to Form Designer. Enter displays the form that was constructed in Form Designer. It can construct a data table, control the data entry process using the settings and check code specified in Form Designer, and provide a search function to locate records that match values specified for any combination of variables or fields on the form. In Enter, the cursor moves from field-to-field and page-to-page automatically saving data. Navigation buttons provide access to new, previous, next, first, and last records, and to their related tables. For more information, see Introduction to Enter. The Analysis module offers two interfaces; Classic and Visual Dashboard. These data may have been collected using Epi Info 7 or another type of database. Currently, Analysis can read data formats in MS Access, Excel, SQL server, and ASCII. It offers simple and intuitive tools to produce many forms of useful statistics and graphs for epidemiologists and other public health professionals.

Epi Info 7 Map shows data from multiple data formats by relating data fields to shape files or through point locations containing X and Y coordinates in various symbols, colors, and sizes. Choropleth and Case-Based are supported. Translation can be done without changing the names of files, and individual translations can be installed or uninstalled without affecting the main programs. Switching from one language to another can be done from the main menu. Settings are used whenever the Classic Analysis module is used. Currently, the record count, data filtering, data recoding, and formatting gadgets are automatically incorporated in the Visual Dashboard module. Additional gadgets can be added with future releases of Epi Info 7. Saving Lives, Protecting People Form Designer is the tool used to design the survey, questionnaire, or form, tailor the data entry process, and specify the tab sequence. It is where you customize any data validation you want to occur when the form receives data in the Enter tool. Each project can have one or many forms which can have one or many pages. On each page, one or many data entry fields are added which collect individual data elements. Field types range from simple labels, text, numeric, and date fields to more advanced fields like drop-down lists, data grids, and command buttons. A list of the available field types is shown in the topic on Fields. Since the process of designing the form also defines the database, the Form Designer can be regarded as a type of database design environment. Epi Info, a suite of lightweight software tools, delivers core ad-hoc epidemiologic functionality without the complexity or expense of large, enterprise applications.
Epi Info is used worldwide for the rapid assessment of disease outbreaks; for the development of small to mid-sized disease surveillance systems; as ad hoc components integrated with other large scale or enterprise-wide public health information systems; and in the continuous education of public health professionals learning the science of epidemiology, tools, and techniques. With Form Designer, users place questions and data entry fields on one or many pages and tailor the data entry process with conditional skip patterns, data validation, and custom calculations programmed by the user using Form Designer's Check Code. Users enter data, modify existing data, or search for records. With Enter, the Forms are displayed and users perform the data entry while the Check Code validates the data or performs any automatic calculations that were specified in Form Designer. In an effort to quickly collect information electronically, the DR2 team has programmed many of the tools in the database. If users are interested in combining multiple forms or using fields from certain forms to build their own custom surveys then they need simply download each one using the instructions below and use Epi Info to create templates. These templates can be combined in the Create Forms module of Epi Info using instructions provided in the Epi Info user guide. To use these instruments, you must first download and install Epi Info from the Centers for Disease Control and Prevention (CDC) website. After installation, go to to search for the instruments you wish to include in your project. Once you find the tools of your choice follow the step by step instructions below: When you search and find an instrument with the icon, right-click on the icon. For instructions, refer to the Epi Info user guide. If entering data directly into the form template, select “Enter Data” above the canvas, authorize the creation of a data table and Epi Info will switch to Data Entry mode.

Open the desired project form or create a new form to transfer to the mobile device. (See Form Designer ). Ensure that the PC recognizes the mobile device in disk drive or media device mode before proceeding to the next step. Before deleting a field, be aware that any data associated with that field will be deleted as well. The data removal is automatic and irreversible. Consider backing up all data prior to deleting a field. Alternatively, use the “Change To” option to change the field to a supported field type. This action can only be performed if a data table is not associated with the form. In order to create a form template, please review the Form Designer chapter of the User’s Manual. Once the form template is created, you can simply copy the form template file (which will have an.XML file extension) into your device or email the form template to yourself or others. Once the file has been copied to your device, it would be recognized by the Companion for Android application and you will be able to begin data collection. WinPepi is available here. Topics covered include univariate statistics, simple statistical inference, charting data, two-by-two tables, stratified analysis, matched analysis, chi-square for trend, logistic regression, survival analysis, computer-intensive methods, and extending R using user-provided functions. The current version of this document is dated 25 th November 2005. It provides easy data entry form and database construction, a customized data entry experience, and data analyses with epidemiologic statistics, maps, and graphs for public health professionals who may lack an informational technology background.It was meant to provide tools for Epidemiologist and field investigators including, sample size calculators, 2X2 table calculators and questionnaires for case-control studies. Since 1998, there have been approximately 2,000,000 successful downloads of Epi Info from the CDC website in 180 countries.
Minicomputer software allowed CDC epidemiologists to develop questionnaires and analyze data through terminals.Epi Info and other database and statistics programs became standard equipment for public health. Translations of the programs or manual appeared in 13 non-English languages. Worldwide copies exceeded 145,000 in 117 countries.More than half of U.S. households have computers. Epi Info 2000 for Windows 95, 98, and NT will bring the benefits of hands-on questionnaire creation, database management, statistics, mapping and graphing to Windows, with Internet enhancements to follow.Andriod application is added and included ability to upload data, and use calculators such as the 2x2 and MxN analyses.It is where you customize any data validation you want to occur when the form receives data in the Enter tool.It acts as a statistical toolbox providing many ways to transform data and perform statistical analyses. Data can be selected, sorted, listed, or manipulated with a series of commands, functions, and operators. Available statistics include frequencies, means, and more advanced processes (i.e., Kaplan-Meier Survival Classic Analysis and Logistic Regression). The Maps tool has the ability to display multiple views from the same dataset. Datasets can be filtered or shown over a series of time using features in the Maps tool. Users can tailor these features to create a customized map containing public health data.Among these tools are a data entry form to calculate z-scores and percentiles as data are entered, growth charting capabilities in the Visual Dashboard, and several nutrition functions in Classic Analysis that you can use to add z-scores and percentiles to existing sets of data.
Three types of calculations are offered:Both single and stratified 2-by-2 tables can be analyzed to produce odds ratios and risk ratios (relative risks) with confidence limits, several types of chi square tests, Fisher exact tests, Mantel-Haenszel summary odds ratios and chi squares, and associated p-values.This tests for the presence of a trend in dose response or other case control studies where a series of increasing or decreasing exposures is being studied.Source code is available at Epi Info's Codeplex website. Web-based data entry, web-based analysis, and mobile data collection tools are currently available and will see continued improvement in 2016 and beyond. As the use of cloud computing increases Epi Info is also adapting to meet the needs of Public Health Informatics as well as Epidemiologist. Because of the worldwide use Epi Info faces many challenges in meeting the needs of so many public health professionals there will likely be changes to come in the interface and also the functionality.

A PLACE Manual Guide for Using Epi Info Software November 005 MS-05-3 Epi Info Guide Lastly, instructions are provided to help you prepare the data and perform the analysis necessary to complete a PLACE report, which will summarize the PLACE findings in your priority prevention areas. This document is presented in the same sequence of data management and analysis activities that are used in a PLACE study. Each of the four sections begins with a summary of the instructions that will follow. A flow chart illustrating the sequence of steps from preparing for data entry through the end of data analysis (Sections -3) is provided on the next page in Figure. The chart indicates which steps are covered within each of the first three sections of this document. Section 4, the final section, provides data use exercises. The two appendices provide information about Epi Info coding and commands. Epi Info is a public domain software package developed by the U.S. Centers for Disease Control and Prevention (CDC). Designed for the global community of public health practitioners and researchers, it provides tools for easy form and database construction, data entry, and analysis with epidemiologic statistics, maps, and graphs. The software can be downloaded from the CDC Web site at: This publication was written for Epi Info Version 6, which was the most current DOS version at time of publication. The instructions will also work with Epi Info Version 3.3., a Windowsbased version that was released in 005.

Epi Info Version 6 is a series of microcomputer programs for handling epidemiologic data in questionnaire format and for organizing study designs and results into text that may form part of written reports.
A questionnaire can be set up and processed in a few minutes, but Epi Info also can form the basis for a powerful disease surveillance system database with many files and record types. It includes features used by epidemiologists in statistical programs, such as SAS or SPSS, and database programs like dbase. Unlike commercial programs, however, Epi Info may be freely copied and given to friends and colleagues. Epi Info allows rapid setup of new entry forms and data files, easily customized data entry, and many data management and analysis techniques. The instructions in this section are based on a learning module from the Northern Health Information Partnership and the Ontario Ministry of Health, Canada. Learning objectives are as follows: You will be able to create a questionnaire using the Epi Info word processor. You will be able to save a questionnaire. You will be able to retrieve a questionnaire for editing. You will be able to enter data into a record file. You will be able to set parameters to aid in the valid entry of data (i.e., to be able to set upper and lower ranges, legal values). You will be able to merge two files. How to Use This Module In many of the examples that follow, you will encounter text in BOLD. This indicates text displayed by EpiInfo or what should be typed into EipInfo. Bold text is also used to indicate keys on your keyboard to be used during the execution of a step (e.g. press F or press Enter. ) This module is intended only to help the user become familiar with Epi Info Version 6. It is not intended to be a complete manual. (The complete manual is available at. There are no Epi Info files for the Venue and Event Report (Form B) because data from Form B will only need to be entered into an Excel spreadsheet. The Epi Info data entry and check files and the cleaning and analysis programs for each of the three questionnaires are provided in the appendix of this document.
Getting Started Double click on the Epi Info icon on your desktop or open the program as you usually do. As you enter the program you will see the following: ENTER data: This part of the program allows you to enter data to a.rec file (or data file). It also allows you to revise the data even after they are entered. ANALYSIS of data: This allows you to tabulate your data, produce frequencies, means, standard deviations, etc. It also allows you to run some basic statistical tests on the data such as chi-squares, odds ratio, relative risks, ANOVA and stratified analysis. CHECK customize entry: This allows you to set upper and lower ranges, legal values, automatic coding, etc.IMPORT files: This ion allows you to bring in data from other programs or in other formats such as dbase, Lotus, ASCII EXPORT files: This allows you to export data from an Epi Info data file to a file format for other software. Most computer programs will accept at least one of the supported formats. MERGE files: Allow you to combine data files and update previous records STATCALC calculator: Calculates statistics from table values that you enter directly from the keyboard. CSAMPLE analyze surveys: Calculates weighted analysis of population surveys (such as the Ontario Health Survey). EPITABLE calculator: This part of the program allows you to compare means, calculate known chisquare, compare proportions, etc. VALIDATE duplicate entry: This is used to compare two Epi Info files entered by different operators and reports any differences. Notes: To increase the screen size, ANALYSIS from the Programs Menu. The Epi Info screen size will increase to fill your computer screen. Return to the Main Menu by pressing F0. File names can only be up to eight characters long in Epi Info Version 6. Epi Info will be unable to open a file if it has a name longer than eight characters. 3 Because of this, it is not necessary for you to create a new data entry screen.
To save time, you may simply modify each questionnaire data entry screen provided that it fits the questionnaires that will be using in your PPAs. If you would like to create a new questionnaire data entry screen, follow these steps: Under the Programs menu, highlight EPED word processor and press Enter. Type in a questionnaire. To save your questionnaire, press F. You will see File Name to Save or no entry to Discard recent work. To save the file you have created type A:\TEST.QES. note that all questionnaires that are to be used later to enter data must have a file type ending QES. Now, your work will have been saved in a file called TEST.QES. Press F0 to exit. If you would like to MODIFY one of the provided PLACE questionnaire data entry screens so that it incorporates changes made to the PLACE questionnaires for your PPA, follow these steps: Under the Programs menu, highlight EPED word processor and press Enter. Press F, and Open File This Window. You will be asked to enter the location and file name of the questionnaire that you want to work with. If the questionnaire is on your CD drive E, for example, and you want to edit the Community Informant Questionnaire, you would type E:\EPIINFO\CI.QES and press enter. Enter any changes you want to make to the questionnaire. Press F0 when you are finished. You will see: Leaving program. To save the changes you have made, press Y; your changes will be saved and you will be returned to the main Epi Info menu. Before you are ready to modify or create data entry screens, you will need to understand the Epi Info symbols that are used in questionnaire data entry screen files. A portion of the first page of the Community Informant Questionnaire (Form A), available as a Word document on the PLACE CD and appearing in the PLACE Manual under the Forms tab, is shown on the next page. The corresponding Epi Info data entry screen appears after the questionnaire. 4.

Before deleting a field, be aware that any data associated with that field will be deleted as well. The data removal is automatic and irreversible. Consider backing up all data prior to deleting a field. Alternatively, use the “Change To” option to change the field to a supported field type. This action can only be performed if a data table is not associated with the form. In order to create a form template, please review the Form Designer chapter of the User’s Manual. Once the form template is created, you can simply copy the form template file (which will have an.XML file extension) into your device or email the form template to yourself or others. Once the file has been copied to your device, it would be recognized by the Companion for Android application and you will be able to begin data collection. WinPepi is available here. Topics covered include univariate statistics, simple statistical inference, charting data, two-by-two tables, stratified analysis, matched analysis, chi-square for trend, logistic regression, survival analysis, computer-intensive methods, and extending R using user-provided functions. The current version of this document is dated 25 th November 2005. It provides easy data entry form and database construction, a customized data entry experience, and data analyses with epidemiologic statistics, maps, and graphs for public health professionals who may lack an informational technology background.It was meant to provide tools for Epidemiologist and field investigators including, sample size calculators, 2X2 table calculators and questionnaires for case-control studies. Since 1998, there have been approximately 2,000,000 successful downloads of Epi Info from the CDC website in 180 countries.
Minicomputer software allowed CDC epidemiologists to develop questionnaires and analyze data through terminals.Epi Info and other database and statistics programs became standard equipment for public health. Translations of the programs or manual appeared in 13 non-English languages. Worldwide copies exceeded 145,000 in 117 countries.More than half of U.S. households have computers. Epi Info 2000 for Windows 95, 98, and NT will bring the benefits of hands-on questionnaire creation, database management, statistics, mapping and graphing to Windows, with Internet enhancements to follow.Andriod application is added and included ability to upload data, and use calculators such as the 2x2 and MxN analyses.It is where you customize any data validation you want to occur when the form receives data in the Enter tool.It acts as a statistical toolbox providing many ways to transform data and perform statistical analyses. Data can be selected, sorted, listed, or manipulated with a series of commands, functions, and operators. Available statistics include frequencies, means, and more advanced processes (i.e., Kaplan-Meier Survival Classic Analysis and Logistic Regression). The Maps tool has the ability to display multiple views from the same dataset. Datasets can be filtered or shown over a series of time using features in the Maps tool. Users can tailor these features to create a customized map containing public health data.Among these tools are a data entry form to calculate z-scores and percentiles as data are entered, growth charting capabilities in the Visual Dashboard, and several nutrition functions in Classic Analysis that you can use to add z-scores and percentiles to existing sets of data.
Three types of calculations are offered:Both single and stratified 2-by-2 tables can be analyzed to produce odds ratios and risk ratios (relative risks) with confidence limits, several types of chi square tests, Fisher exact tests, Mantel-Haenszel summary odds ratios and chi squares, and associated p-values.This tests for the presence of a trend in dose response or other case control studies where a series of increasing or decreasing exposures is being studied.Source code is available at Epi Info's Codeplex website. Web-based data entry, web-based analysis, and mobile data collection tools are currently available and will see continued improvement in 2016 and beyond. As the use of cloud computing increases Epi Info is also adapting to meet the needs of Public Health Informatics as well as Epidemiologist. Because of the worldwide use Epi Info faces many challenges in meeting the needs of so many public health professionals there will likely be changes to come in the interface and also the functionality.

A PLACE Manual Guide for Using Epi Info Software November 005 MS-05-3 Epi Info Guide Lastly, instructions are provided to help you prepare the data and perform the analysis necessary to complete a PLACE report, which will summarize the PLACE findings in your priority prevention areas. This document is presented in the same sequence of data management and analysis activities that are used in a PLACE study. Each of the four sections begins with a summary of the instructions that will follow. A flow chart illustrating the sequence of steps from preparing for data entry through the end of data analysis (Sections -3) is provided on the next page in Figure. The chart indicates which steps are covered within each of the first three sections of this document. Section 4, the final section, provides data use exercises. The two appendices provide information about Epi Info coding and commands. Epi Info is a public domain software package developed by the U.S. Centers for Disease Control and Prevention (CDC). Designed for the global community of public health practitioners and researchers, it provides tools for easy form and database construction, data entry, and analysis with epidemiologic statistics, maps, and graphs. The software can be downloaded from the CDC Web site at: This publication was written for Epi Info Version 6, which was the most current DOS version at time of publication. The instructions will also work with Epi Info Version 3.3., a Windowsbased version that was released in 005. A complete manual for Version 6 can be accessed at the CDC Web site at: Tutorials on how to use Epi Info are also available at CDC, at: System requirements for using Epi Info for Windows are as follows: Windows 8, NT 4.0, 000, or XP is required; 3 MB of RAM (64 MB for Windows 4.

Epi Info Version 6 is a series of microcomputer programs for handling epidemiologic data in questionnaire format and for organizing study designs and results into text that may form part of written reports.
A questionnaire can be set up and processed in a few minutes, but Epi Info also can form the basis for a powerful disease surveillance system database with many files and record types. It includes features used by epidemiologists in statistical programs, such as SAS or SPSS, and database programs like dbase. Unlike commercial programs, however, Epi Info may be freely copied and given to friends and colleagues. Epi Info allows rapid setup of new entry forms and data files, easily customized data entry, and many data management and analysis techniques. The instructions in this section are based on a learning module from the Northern Health Information Partnership and the Ontario Ministry of Health, Canada. Learning objectives are as follows: You will be able to create a questionnaire using the Epi Info word processor. You will be able to save a questionnaire. You will be able to retrieve a questionnaire for editing. You will be able to enter data into a record file. You will be able to set parameters to aid in the valid entry of data (i.e., to be able to set upper and lower ranges, legal values). You will be able to merge two files. How to Use This Module In many of the examples that follow, you will encounter text in BOLD. This indicates text displayed by EpiInfo or what should be typed into EipInfo. Bold text is also used to indicate keys on your keyboard to be used during the execution of a step (e.g. press F or press Enter. ) This module is intended only to help the user become familiar with Epi Info Version 6. It is not intended to be a complete manual. (The complete manual is available at. There are no Epi Info files for the Venue and Event Report (Form B) because data from Form B will only need to be entered into an Excel spreadsheet. The Epi Info data entry and check files and the cleaning and analysis programs for each of the three questionnaires are provided in the appendix of this document.
Getting Started Double click on the Epi Info icon on your desktop or open the program as you usually do. As you enter the program you will see the following: ENTER data: This part of the program allows you to enter data to a.rec file (or data file). It also allows you to revise the data even after they are entered. ANALYSIS of data: This allows you to tabulate your data, produce frequencies, means, standard deviations, etc. It also allows you to run some basic statistical tests on the data such as chi-squares, odds ratio, relative risks, ANOVA and stratified analysis. CHECK customize entry: This allows you to set upper and lower ranges, legal values, automatic coding, etc.IMPORT files: This ion allows you to bring in data from other programs or in other formats such as dbase, Lotus, ASCII EXPORT files: This allows you to export data from an Epi Info data file to a file format for other software. Most computer programs will accept at least one of the supported formats. MERGE files: Allow you to combine data files and update previous records STATCALC calculator: Calculates statistics from table values that you enter directly from the keyboard. CSAMPLE analyze surveys: Calculates weighted analysis of population surveys (such as the Ontario Health Survey). EPITABLE calculator: This part of the program allows you to compare means, calculate known chisquare, compare proportions, etc. VALIDATE duplicate entry: This is used to compare two Epi Info files entered by different operators and reports any differences. Notes: To increase the screen size, ANALYSIS from the Programs Menu. The Epi Info screen size will increase to fill your computer screen. Return to the Main Menu by pressing F0. File names can only be up to eight characters long in Epi Info Version 6. Epi Info will be unable to open a file if it has a name longer than eight characters. 3 Because of this, it is not necessary for you to create a new data entry screen.
To save time, you may simply modify each questionnaire data entry screen provided that it fits the questionnaires that will be using in your PPAs. If you would like to create a new questionnaire data entry screen, follow these steps: Under the Programs menu, highlight EPED word processor and press Enter. Type in a questionnaire. To save your questionnaire, press F. You will see File Name to Save or no entry to Discard recent work. To save the file you have created type A:\TEST.QES. note that all questionnaires that are to be used later to enter data must have a file type ending QES. Now, your work will have been saved in a file called TEST.QES. Press F0 to exit. If you would like to MODIFY one of the provided PLACE questionnaire data entry screens so that it incorporates changes made to the PLACE questionnaires for your PPA, follow these steps: Under the Programs menu, highlight EPED word processor and press Enter. Press F, and Open File This Window. You will be asked to enter the location and file name of the questionnaire that you want to work with. If the questionnaire is on your CD drive E, for example, and you want to edit the Community Informant Questionnaire, you would type E:\EPIINFO\CI.QES and press enter. Enter any changes you want to make to the questionnaire. Press F0 when you are finished. You will see: Leaving program. To save the changes you have made, press Y; your changes will be saved and you will be returned to the main Epi Info menu. Before you are ready to modify or create data entry screens, you will need to understand the Epi Info symbols that are used in questionnaire data entry screen files. A portion of the first page of the Community Informant Questionnaire (Form A), available as a Word document on the PLACE CD and appearing in the PLACE Manual under the Forms tab, is shown on the next page. The corresponding Epi Info data entry screen appears after the questionnaire. 4.
