^*P-values are testing for differences in LOS between groups using a Kruskal-Wallis test.

^†P-values are testing for statistical significance in the multivariable negative binomial regression.

Abbreviations: LOS, length of stay; LOSR, length of stay ratio; IQR, interquartile range; PELD/MELD, pediatric end-stage liver disease/model for end-stage liver disease; ESLD, end-stage liver disease.
