Fig. 2From: Long-term outcomes of prediction error after combined phacoemulsification and trabeculectomy in glaucoma patientsGraphs showing the ROC curve of LV for unstable prediction error at 12 months postoperatively (a) and at 24 months postoperatively (b). The AUC of (a) was 0.619 and the AUC of (b) was 0.689. The cut-off value of LV was 0.855 mm in both (a) and (b). ROC = receiver operating characteristic; LV = lens vault; AUC = area under the curveBack to article page
