FIG 4. Scatterplots demonstrate negative correlations between mean diffusivity measures in the hippocampus of patients with mesial temporal sclerosis and multiple neuropsychological tests assessing verbal memory (delayed recall [DR] and new word [REC]) and visuospatial memory (RD). Each data point corresponds to the average apparent diffusion coefficient (ADC) measure in the specified region for a single patient. Error bars indicate ±1 standard deviation derived from multiple readings and multiple readers. Correlation coefficients are calculated using a mixed-model analysis. Solid lines and solid data points indicate statistically significant findings (P < .05) using non-Bonferroni adjusted significance levels. Dotted line and hollow data points indicate that the relationship does not reach statistical significance.
A. Left hippocampal ADC correlation with DR.
B. Left hippocampal ADC correlation with REC.
C. Left hippocampal ADC correlation with RD.
D. Right hippocampal ADC correlation with REC.
E. Right hippocampal ADC correlation with RD (P = .08).
