$Overview of observed standardized regression coefficients (b values) for the associations between total body fat and fractional anisotropy (FA)- and mean diffusivity (MD)-based DTI tracts for men and women. Standardized regression coefficients reflect the standard deviation (SD) change in FA and MD, respectively, per standard deviation (6.5% in women and 5.5% in men) change in total body fat. Results were adjusted for age, ethnicity, Townsend deprivation index, assessment center (baseline visit and imaging visit), smoking, alcohol use, diabetes, cardiovascular disease, and intracranial volume.
