Body mass at weaning (3 weeks of age) and as adults (just prior to wheel testing, 7-11 weeks of age) of C and HR mice given maternal SD or WD, with separate analyses for females and males. Bars are age-adjusted LSM + SE and N were approximately equal for each group. Striped bars indicate maternal standard diet, solid bars indicate maternal Western diet, grey bars are control mice, and black bars are high-runner (HR) mice. Results of statistical analyses (fixed effects) are shown above each graph. All analyses included covariates of age (not shown).
