Clinical evidences are quantified by a number of indicators. R is a free and powerful environment for statistical computing and graphics, used mainly in command line interface. The <strong>aim</strong> of this work was to create an extension for R Commander to offer a graphical user interface to calculate the most used EBM indicators. <strong><em>Materials and Methods:</em></strong> The extension was created in R and then tested in R 3.1.1 and R Commander 2.1-1. <strong><em>Results:</em></strong> The extension was successfully created and was named RcmdrPlugin.EBM, being available for download on Comprehensive R Archive Network servers. The extension creates a new menu called EBM, which offers an interface to calculate the following indicators with their confidence intervals: diagnosis (sensitivity, specificity, diagnostic accuracy, Youden’s index, positive/negative likelihood ratio, positive/negative predictive value, number needed to diagnose), therapeutic (absolute risk reduction, relative risk reduction, odds ratio, relative risk, number needed to treat/harm), prognostic (attributable risk, relative risk, odds ratio). <strong><em>Conclusion:</em></strong> It is now easy to compute EBM indicators in R, with the graphical user interface extension of R Commander.}, number={3}, journal={Applied Medical Informatics}, author={LEUCUȚA, Daniel Corneliu and CĂLINICI, Tudor and DRUGAN, Tudor and ISTRATE, Dan and ACHIMAȘ, Andrei}, year={2014}, month={Sep.}, pages={11–16} }
