ROC curves for SS-OIT. A-D) Comparison of multinomial AUC (MoCA + SS-OIT) to MoCA only AUC for diagnostic accuracy. The addition of SS-OIT to the MoCA significantly improved overall prediction between MCI and HOA. E) AUC, sensitivity and specificity, Youden index, optimal cut-off score, and diagnostic classification accuracy for the MoCA, SS-OIT, and MoCA + SS-OIT.
