Figure 1 Mean volumes and atrophy rates

Box plots of (A) baseline hippocampal volume, (B) hippocampal atrophy rate, (C) baseline whole brain volume, and (D) whole brain atrophy rate per diagnostic group (controls, mild cognitive impairment [MCI], and Alzheimer disease [AD]), and box plots of patients with MCI who remained stable and those who progressed to AD for (E) hippocampal atrophy rate and (F) whole brain atrophy rate. Lines represent median; boxes, interquartile range; and whiskers, range; o = outliers. *p < 0.005.
