Fig. 3: Bar charts for resting energy expenditure parameters of the indirect calorimetry in the analysis population with complete outcome data (n = 26).

Differences in A basal resting metabolic rate, B metabolic to the predicted rate of resting energy expenditure, C basal respiratory quotient, and D nitrogen output over time were tested with repeated measures ANOVA and are shown as p-values. FFM, fat-free mass; mREE, measured resting energy expenditure; pREE, predicted resting energy expenditure; RMR, resting metabolic rate; RQ, respiratory quotient; VCO2, carbon dioxide production; VO2, oxygen consumption.
