FIG 5. Scatterplot demonstrates a positive correlation between right parahippocampal apparent diffusion coefficient (ADC) measures and visuospatial memory test scores. Data points and error bars represent average ADC and standard deviation based on multiple readers and multiple readings. The correlation coefficient is calculated by using mixed-model analysis. Non-Bonferroni adjusted statistically significant positive correlation (P < .05) is seen between right parahippocampal ADC and BV2 (measure of delayed recall at 30 minutes). The relationship between right parahippocampal ADC and BV1 (measure of immediate recall) does not reach statistical significance (P = .09).
