ROC curves of individual subject classification to sMCI or pMCI.

<p>ROC curves of individual subject classification to sMCI or pMCI based on baseline <i>BrainAGE</i> scores, cognitive scores, and hippocampus volumes for (A) early converters and (B) the whole sample. The areas under the ROC curves (AUCs) of cognitive scores and hippocampus volumes were tested against the AUC of <i>BrainAGE</i>: ***p<0.001; **p<0.01; *p<0.05.
