Relational database modeling is supported, as users may link their form to any number of other forms in their database. Skip patterns, message boxes, and math operations are also available.

For example, if the data entry person types 'Male' into a question on gender, any questions relating to pregnancy might then be hidden or disabled.

Check code allows for certain events to occur depending on what action a data entry person has taken. One of the more powerful features of Form Designer is the ability to program intelligence into a form through a feature called 'check code'. Users can also create drop-down lists, code tables, and comment legal fields. Data types include numbers, text strings, dates, times, and Boolean.

The user defines both the question's prompt and the format of the data that is to be collected. The user is given a high degree of control over the form's appearance and function. Individual questions can be placed anywhere on a page and each form may contain multiple pages. Other modules include the Report module, a mapping module, a menu module, and various utilities such as StatCalc.Įlectronic questionnaires are created in the Form Designer module. For epidemiological uses, such as outbreak investigations, being able to rapidly create an electronic data entry screen and then do immediate analysis on the collected data can save considerable amounts of time versus using paper surveys.Įpi Info uses three distinct modules to accomplish these tasks: Form Designer, Enter, and Analysis. The next iteration of the Epi Info series, Epi Info 7, was made open source on Novemwhen its source code was uploaded to Codeplex for the first time.įrom a user's perspective, one of the most important functions of Epi Info is the ability to rapidly develop a questionnaire, customize the data entry process, quickly enter data into that questionnaire, and then analyze the data.

The 7 series is the presently maintained Epi Info product line. Following the release of Epi Info 2000 was Epi Info 2002, then Epi Info version 3.0, and finally the open-source Epi Info 7. The last MS-DOS version was Epi Info 6.04d released in January 2001.Įpi Info 2000 changed the way data was stored by adopting the Microsoft Access database format, rather than continuing to use the plain-text file format from the MS-DOS versions. MS-DOS continued to be the only supported operating system until the release of Epi Info 2000, which was written in Microsoft's Visual Basic and became the first Windows-compatible version.

The first version, Epi Info 1, was originally implemented as an MS-DOS batch file on 5.25' floppy disks and released in 1985. Įpi Info has been in development for over 20 years. Limited support is available.Īn analysis conducted in 2003 documented over 1,000,000 downloads of Epi Info from 180 countries.

The software is in the public domain, free, and can be downloaded from. Within the analysis module, analytic routines include t-tests, ANOVA, nonparametric statistics, cross tabulations and stratification with estimates of odds ratios, risk ratios, and risk differences, logistic regression (conditional and unconditional), survival analysis (Kaplan Meier and Cox proportional hazard), and analysis of complex survey data. The program allows for electronic survey creation, data entry, and analysis. Epi Info is public domain statistical software for epidemiology developed by Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia (USA).Įpi Info has been in existence for over 20 years and is currently available for Microsoft Windows.
