ROC Curve / Diagnostic Screening Analysis
Measure a diagnostic test's/biomarker's discriminative power with AUC, the optimal cutoff point, and a sensitivity/specificity table. Includes the option to compare two tests with the DeLong test.
ROC Curve & AUC
The AUC value is reported with the Hanley-McNeil 95% confidence interval.
Optimal Cutoff Point
The best cutoff point according to the Youden J index, along with the sensitivity/specificity/PPV/NPV/LR+/LR- table at that point.
Two-Test Comparison
The AUC difference between two tests on the same sample is tested with the DeLong test.
