Figure 1. Receiver-Operating Characteristic (ROC) for KnowPain-12.

Figure 1

Legend

A receiver-operating characteristic (ROC) curve plots the sensitivity versus the false positive rate for different thresholds of the KnowPain-12 score. The closer the ROC is to the upper left corner, the greater the ability of the score to distinguish between the two groups.
