^*Data presented as median (IQR).

^†LR-any group included patients who received any amount of LR fluid resuscitation.

^‡NS group included patients who received only NS fluid resuscitation.

^§Statistical comparison using McNemar test for matched pairs or Wilcoxon sign rank test, as appropriate.

^¶LOS is reported in days.

^**LR-only group included patients who only received LR fluid resuscitation.
