ANCOVA with sex as a covariate showed that group differences in body composition were robust to sex adjustment ( Table 2 ): for PBF, F _group (3,52) = 14.11 ( p < .001), and the sex covariate itself was highly significant ( F _sex = 30.18, p < .001), indicating that although sex distribution did not differ across groups, sex strongly predicted body composition within groups.
