Resting energy expenditure (REE) in the study population (box-and-whiskers) with indication of individual data (solid lines) during spontaneous breathing (REESB) and noninvasive ventilation (REE _NIV ). The limits of the boxes correspond to the 25th and 75th percentiles of the distribution, with indication of the median as the black solid lines within the boxes. The whiskers represent the 10th and the 90th percentiles, respectively, and the black dots indicate the extreme values. The gray area corresponds to the interquartile space of REE predicted according to the equation of Harris and Benedict.
