... that lean body mass (LBM) was highly correlated with good method agreement using DEXA as the reference test (r = 0.95, p < 0.0001; bias –0.88 kg, 95% CI –1.53 to 0.23 kg). Similarly, high correlation and good method agreement were found for fat mass (r = 0.93, p < 0.0001; bias 0.69 kg, 95% CI 0.03...
