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. 
• ROC curve graph with 95% Confidence Bounds. 
• 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. 
• Go to the ROC curve analysis section of the MedCalc manual for more information on ROC curve analysis in MedCalc.
