Stepwise linear regression analysis was used to derive a new REE equation (eREE-PD) based on actual REE (aREE) measured using indirect calorimetry (IC) in the development dataset. The eREE-PD value was then validated with aREE in the validation dataset and compared with values from existing equations obtained in general populations and those developed for chronic kidney disease and dialysis patients, in terms of bias, precision, and accuracy.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The bias, precision, and accuracy of the eREE-PD equation were significantly better than those of the Harris\u2013Benedict, WHO, and Schofield equations (P\u00a0&amp;lt;\u00a0.005) and comparable to the Mifflin equation (P\u00a0=\u00a0.541 for bias, .988 for precision, and .359 for accuracy), with IC as the reference method. Either bias, precision or accuracy of the eREE-PD were significantly better than eREE-V, eREE-Bscr, and eREE-CFFM equations significantly (P\u00a0&amp;lt;\u00a0.005) and similar to eREE-CKD, eREE-Bcrp, and eREE-Cweighht equations (P\u00a0&amp;gt;\u00a0.05 for bias, precision, and accuracy).
