Mean (±SEM) whole-body protein metabolism in critically ill infants receiving protein-energy–enriched formula (n = 8) or standard formula (n = 10). *Comparisons between the PE-formula and S-formula were performed by using Wilcoxon's rank-sum test, P < 0.05. PE-formula, protein-energy–enriched enteral formula; PE-group, protein-energy–enriched formula–fed infants with viral bronchiolitis (n = 8); S-formula, standard infant formula; S-group, standard formula–fed infants with viral bronchiolitis (n = 10); WB net PS, whole-body net protein synthesis; WB PB, whole-body protein breakdown; WB PS, whole-body protein synthesis.
