Comparison of the optimized random forest models trained on the demographic and ocular (DO) features and systemic, demographic and ocular (SDO) features.

Case study	Accuracy	Sensitivity	Specificity	AUC	PPV	NPV
DO features	0.67	0.49	0.86	0.68	0.71	0.64
SDO features	0.68	0.60	0.76	0.74	0.69	0.65

AUC = area under the receiver operating characteristic curve; PPV = positive predictive value; NPV = negative predictive value.
