Receiver operating characteristic (ROC) analyses. ROC analysis to identify the threshold value of DCTL, TLHCobb’s and TLCobb’s. DCTLs of 8.7°, 7.5° and 9.2° were determined using the ROC curve of reciprocal DCTL and Youden’s index. The three lines showed the differences among DCTL, TLHCobb’s and TLCobb’s (a). Reciprocal DCTL line presented the higher accuracy of detection than TLHCobb’s and TLCobb’s lines (b, c and d), and a threshold value of 8.7° with a sensitivity of 78. 4%, a specificity of 74.3%, and an AUC of 0.783 (95% CI of 0.613–0.953)
