Bias, mean percentage error between predictive equation and measured value; RMSE, root mean sum of squared prediction error; Maximum negative error, the largest underprediction that was found with this predictive equation as a percentage of the measured value; Maximum positive error, the largest over-prediction that was found with this predictive equation as a percentage of the measured value; Accurate predictions, the percentage of subjects predicted by this equation within 10% of the measured value; Under-predictions, the percentage of subjects predicted by this equation <10% of the measured value; Over-predictions, the percentage of subjects predicted by this equation >10% of the measured value; Henry_WH30–60, Henry's predictive equation based on weight and height for age group 30–60 years; Livingston, Livingston's predictive equation based on weight and age; Müller_FFMall, Müller's predictive equation based on FFM, FM and age for all BMI groups; Müller_FFM30, Müller's predictive equation based on FFM, FM and age for BMI group ≥ 30 kg/m²; Johnstone_FFM, Johnstone's predictive equation based on FFM, FM and age; Lazzer_FFM, Lazzer's predictive equation based on FFM and FM for BMI group ≥ 40 kg/m².
