Grouping variables were expressed as frequency (rate), while numerical values were expressed as mean ± standard deviation. P > 0.05, compared with males of validation participants. #P > 0.05, compared with females of validation participants. Abbreviations: LBM_DXA, lean body mass measured by dual-energy X-ray absorptiometry.
