Figure.

Receiver operating characteristic (ROC) curve for different changes in upper-extremity portion of the Fugl-Meyer Scale scores for distinguishing participants who demonstrated important improvement from those who did not have important improvement. Sensitivity values (true positive rate) on the y-axis and 1 − specificity values (false positive rate) on the x-axis. AUC=area under curve, COPM=Canadian Occupational Performance Measure.
