FIG 2. A–C, Scatter plots for subjects with AD and combined MCI and VaD by age for brain volume (A), hippocampal volume (B), and VBR (C) based on the following correlations: Brain volume, r{epsilon}4- = -.26, P <= .01; r{epsilon}4+ = -0.19, P <= .01; hippocampal volume, r{epsilon}4- = 0.17, P <= .05; r{epsilon}4+ = 0.01, P > .05; and VBR, r{epsilon}4- = -.34, P <= .01; r{epsilon}4+ = 0.13, P <= .05
