ROC curves, test accuracy, and the description of diagnostic tests.
Clinicians can gain an enhanced understanding of the role of diagnostic tests once they are familiar and comfortable with the descriptions of test performance provided by receiver operating characteristic (ROC) analysis. This article explores the ways that ROC methods quantify test accuracy and describes how ROC methods characterize the distributions of test outcomes in study populations.
