MedCalc is a complete statistical program for Windows designed to closely match the requirements of biomedical researchers. It is fast, user-friendly and reliable. MedCalc is the most user-friendly software for Receiver Operating Characteristic curve (ROC curves) analysis. The MedCalc ROC module includes comparison of up to 6 ROC curves. The software also includes Bland & Altman plot, Passing and Bablok and Deming regression for method comparison studies.

ROC curve analysis

* Area under the curve (AUC) with standard error, 95% confidence interval, P-value. Offers choice between methodology of DeLong et al. (1988) and Hanley & McNeil (1982 1983).
* List of sensitivity, specificity, likelihood ratios, and positive and negative predictive values for all possible threshold values.

* Threshold values can be selected in an interactive dot diagram with automatic calculation of corresponding sensitivity and specificity.
* Plot of sensitivity and specificity versus criterion values.
* Interval likelihood ratios.
* Comparison of up to 6 ROC curves: difference between the areas under the ROC curves, with standard error, 95% confidence interval and P-value.
* Sample size calculation for area under ROC curve and comparison of ROC curves.
