Table 3.
Bone outcomes separated by group and sex. Values are mean ± standard deviation; P values for post hoc comparison between groups are shown after adjustment for sex. Adjustments: M1, adjusted for sex, height, and age; M2, M1 + fat mass; M3, M1 + lean mass; M4, M1+ fat mass + lean mass; M5, M4+ absolute power
