For categorical variables, n (%) is presented. For continuous variables, mean (SD)/median (min; max)/n= is presented. For comparison between groups, Fisher’s exact test (lowest 1-sided p-value multiplied by 2) was used for dichotomous variables, the Mantel-Haenszel Chi Square test was used for ordered categorical variables, and the Mann–Whitney U test was used for continuous variables. NICU: neonatal intensive care unit.
