Read below about how to remove it from your computer. The Windows release was created by CDC. More information about CDC can be read here. You can read more about on Epi Info 7 at. Many of the modules have a “Load Demo Data” button that will automatically load example data into the module.A guide to uninstall Epi Info 7 from your systemEpi Info 7 is a Windows program. Other links on the screen include “Documentation,” which provides the analytic details, including formulae, used in the module and “Testing,” which compares the results of the OpenEpi module to other software programs or to textbook examples. And a “Help” tab is available to answer questions about the program. A number of examples are provided under the “Examples” tab. Results of the calculations are under the “Results” tab. The “Enter” tab is where data entry is performed, or the user can click on the “Enter New Data” button. The “Start” tab provides an overview of the module. Finally, with count data, OpenEpi also performs a test for trend, for both crude and stratified data.Īn example of one of the modules is shown in Figure 2, which features five tabs. With rate data, OpenEpi provides adjusted rate ratios and rate differences, and tests for interaction. Similar to Epi Info, in a stratified analysis, both crude and adjusted estimates are provided so that the assessment of confounding can be made. A recent Google search identified almost 5,000 sites mentioning OpenEpi. OpenEpi has had more than 1.4 million hits from 160 countries since its inception in 2003 and almost 500,000 hits in the first six months of 2008. The initial development of OpenEpi was supported by a grant from the Bill and Melinda Gates Foundation to Emory University. OpenEpi, Epi Info, and EpiData were developed with the goal of providing simple tools for low- and moderate-resource areas of the world. We see OpenEpi as a useful companion to Epi Info and to other programs such as SAS, SPSS, Stata, and EpiData. It is the first step toward an entirely Web-based suite of epidemiologic software tools. OpenEpi was initially developed to perform analyses found in the disk operating system (DOS) version of Epi Info modules StatCalc and EpiTable, to improve on the types of analyses provided by these modules, and to provide a number of tools and calculations not currently available in Epi Info. The OpenEpi developers have had extensive experience in developing and testing Epi Info, a program developed by the Centers for Disease Control and Prevention (CDC) and used worldwide for data entry and analysis. The program is available in English, French, Italian, and Spanish. The source code and documentation are freely downloadable and available for use by other investigators. The program can be run from the OpenEpi website or downloaded and run without a Web connection. Therefore, it can run under various Web browsers, such as Microsoft ® Explorer, Firefox ®, Safari, and Opera, and on a number of operating systems, such as Windows, Macintosh, and Linux. 2 – 7 OpenEpi was developed in JavaScript and hypertext markup language (HTML) and can be run in browsers supporting these languages. OpenEpi ( is a free, Web-based, open-source, operating system-independent series of programs designed for use in public health and medicine-for training or practice-that provide a number of epidemiologic and statistical tools for summary data. Because of the aforementioned limitations, we decided to develop a program to assist in teaching epidemiologic and statistical procedures. For some of the commercial and free programs mentioned, many epidemiologic parameters and statistical calculations taught in SPH courses are not provided in the programs. While they are probably the most commonly used commercial programs in epidemiology, 1 and are incredibly powerful, they do have certain characteristics that limit their use in low- to moderate-resource situations: ( 1) they tend to be expensive beyond the reach of some SPHs worldwide, ( 2) they tend to be complicated to learn and use, ( 3) they have a number of hardware/computer requirements, and ( 4) user support may not be readily available.įree epidemiologic programs, such as Epi Info ( and EpiData ( are also available. A number of commercial programs are available, many of which are taught in schools of public health (SPHs), such as SAS ®, SPSS ®, and Stata ®. Frequently, many of these may be initially calculated by hand with a calculator and then later using computer software. During graduate training in public health, students are exposed to a number of epidemiologic and statistical formulae.
