AKI, acute kidney injury; IVH, intraventricular hemorrhage
* To test for differences between groups we used independent samples t tests for continuous variables, Wilcoxon rank-sum test for medians, χ2 tests for categorical variables (Fisher exact test for cells <5), and log rank test for equality of survivor functions.
† Values are statistically significant.
