Receiver operating characteristic (ROC). The ROC curve shows relation between true-positive rate (sensitivity) and false-positive rate (1-specificity) of MRI-JSN based on XR-JSN as the gold standard, as the MRI-JSN positivity criterion is increased from 0.0 to 4.0. The prominent shift of the curve to the left of the no-discrimination line (broken line) is indicative of the high discriminative power of MRI for JSN.
