Table 3 shows the area under the curve (AUROC) and confidence interval (CI) of the receiver operating characteristic (ROC) curves (see Fig. 3) for the prognostic parameters analyzed in the regression models. The cutoff value was derived according to the maximum value of Youden’s index (J). Sensitivity and specificity show the highest possible values at the cutoff value. Abbreviations: CI confidence interval, MLD minimum linear diameter, BD base diameter; H max. Height, Ar area of MH, Cy area of pseudocysts, VA visual acuity
