www.equator-network.orgWhen multiple such cut-offs can be defined, authors can report a receiver operating characteristic (ROC) curve which graphically represents the combination of sensitivity and specificity for each possible test positivity cut-off. The area under the ROC curve informs in a single numerical value about the overall diagnostic accuracy of the index ...

lexjansen.comsensitivity). These pairs constitute the Receiver Operating Characteristic (ROC) curve. Points far above the 45 degree line are desirable and one hopes to have this curve rise as quickly as possible from the origin. The 45 degree line in the unit square would correspond to an area under the curve (AUC) of 0.5
