Fig. 2 Graph shows receiver operating characteristic (ROC) curves of
predicted probability of amnestic mild cognitive impairment based on
hippocampal volumes compared with Mini-Mental State Examination (MMSE) score.
Solid line indicates area under ROC curve (AUC) of 0.886 for left hippocampal
volume; dashed line, AUC of 0.745 for MMSE; dotted line, AUC of 0.614 for
right hippocampal volume.

Fig. 3 Graph shows receiver operating characteristic (ROC) curve of
predicted probability of amnestic mild cognitive impairment calculated from
combined left hippocampal volume and Mini-Mental State Examination (MMSE)
score compared with predicted probability based on MMSE score alone. Solid
line indicates area under ROC curve (AUC) of 0.918 for combination of left
hippocampal volume and MMSE; dotted line, AUC of 0.745 for MMSE.
