1. a plot of percentage of true positive results versus percentage of false positive results, usually in a trial of a diagnostic test.
2. a graphic means of assessing the ability of a screening test to discriminate between healthy and diseased people.
Synonym(s): ROC curve

receiver operating characteristic (ROC) curve

a curve that plots the true-positive fraction versus false-positive fraction; one use is to evaluate imaging performance.

ROC curve

Receiver operating characteristic curve. A graphic depiction of the relationship between the true positive ratio (sensitivity) and false positive ratio (1) specificity as a function of the cut-off level of a disease or condition marker.
