Fig. 6From: Predicting visual acuity in Bietti crystalline dystrophy: evaluation of image parametersReceiver-operating characteristic (ROC) for two factors. “EZ disruption at fovea” (the dot line) showed the largest area under the curve (AUC) of 0.868, indicating the best discriminatory power. The AUCs of foveal choroidal thickness (the grey line) was 0.802 (EZ ellipsoid zone)Back to article page
