Fig. 1From: Hole diameter ratio for prediction of anatomical outcomes in stage III or IV idiopathic macular holesThe area under the receiver operating characteristic curve of preoperative hole diameter ratio (HDR) for predicting postoperative macular hole closure. The area under the curve was 0.680 (95% confidence interval 0.559–0.801). When the cutoff value of HDR was set at 0.6, the predicting sensitivity and specificity were 75.0 and 67.9%, respectively (P = 0.01)Back to article page
