ROC (receiver operating characteristic) curve and the results of pairwise comparison of ROC curves of reader 1 (a), reader 2 (b) and reader 3 (c). Labels: AADI(N) = AADI method in neutral posture; AADI (F) = AADI method in flexion posture; Swischuk (N) = Swischuk line in neutral posture; Swischuk (F) = Swischuk line in flexion posture; AUC = area under curve. Numbers in parentheses indicate the 95% confidence interval.An asterisk (*) indicates statistically significant results (P < 0.005). Optimal cutoff values by using the maximum Youden index (sensitivity + specificity − 1) for each ROC curve were represented by an empty circle point
