The results are standardized regression coefficients and 95% CI in parentheses for the lowest versus highest socioeconomic group; models adjusted for age, age square, sex, and total intracranial volume; MD, mean diffusivity; MT, magnetization transfer; R2*, transverse relaxation rate; ICVF, intracellular volume fraction; ISOVF, isotropic volume fraction; OD, orientation dispersion index.
