  • Data are medians (25th–75th percentiles). BMR is estimated by the Schofield equation. PICU, pediatric intensive care unit; BMR, basal metabolic rate.

  • a Mann-Whitney test.

  • b Actual energy or protein intake versus BMR or recommended protein intake, respectively. Wilcoxon signed rank test (P<0.001).

  • c Percentage of protein needs versus percentage BMR. Wilcoxon signed rank test (P<0.001).
