Model adjusted for participant sex, age, education level and weight at time of assessment and maternal education and land ownership. Percent difference in RHI estimated by back-transformation of beta estimate of natural log transformed reactive hyperemia index (lnRHI). Missing maternal education and land ownership for one participant reduced sample size to N=199.
