MCI prediction.

<p>AD = Alzheimer's disease, MCI = Mild Cognitive Impairment, CTL = healthy control, MCI-c = MCI converters and MCI-s = MCI stable. To better compare the performance of the three methods we also calculated the sensitivity (MCI-c predicted as AD) at a fixed specificity (MCI-s predicted as CTL). We set the specificity to that of the visual rating assessment and recalculated the sensitivity and specificity of the other two methods used.
