Statistical software for biomedical research, including ROC curve analysis.

MedCalc is a useful and stand-alone computer application for statistics in the biomedical sciences. It has an integrated spreadsheet which can be configured to contain up to 100000 rows. The program correctly handles missing data and provides reliable date arithmetic.

MedCalc can import Excel, SPSS, DBase and Lotus files, and files in SYLK, DIF or text format. Comprehensive on line help is available and, in addition to a manual in PDF format, a complete user manual is available on the web.
 
The program calculates the area under the curve (AUC) with its standard error and 95% confidence interval. Furthermore, threshold values can be selected in an interactive dot diagram with automatic calculation of corresponding sensitivity and specificity.

Comparison of ROC curves includes calculation of the difference between the areas under the curves, with standard error, 95% confidence interval and P-value.
