Forest plot of beta coefficients from linear regression of brain atrophy and DTI metrics. The forest plots display the standardized beta coefficients from linear regression analyses with 95% confidence intervals, adjusted for age, sex, BMI, APOE4 genotype, and ICV. The forest plots show each regressor’s standardized beta linear regression coefficients with 95% confidence interval. Plots displaying the beta coefficients from linear regression analyses of cortical thickness with FA, MD, and FW (A), as well as hippocampal volume with FA, MD, and FW (B). FA, fractional anisotropy; MD, mean diffusivity; FW, free water.
