Categorical data are presented as number (percent) and compared using 2-sided Pearson’s Chi-squared test. Continuous data are presented as median (interquartile range) and compared using 2-tailed Mann-Whitney test. CRRT: continuous renal replacement therapy. PRBC: packed red blood cell.
Days from traumatic insult to initiation of CRRT.
