  1. aP value of comparison between REEm and REEe; bP value of comparison of REEe between ideal body weight and current body weight; end of the predictive equations’ name plus ‘-s’ means that REE was calculated by ideal body weight, otherwise by current body weight. H-B, Harris-Benedict; IC, indirect calorimetry; REE, resting energy expenditure; REEe, estimated REE; REEm, measured REE; WHO, World Health Organization.
