Values in “n” columns are numbers of patients with data available. P values are given for the median score test. MI, Myocardial infarction; ICU, intensive care unit.

^*15th/50th/85th percentiles. Median score test was used to compare medians and Wilcoxon rank-sum test to compare tails of distributions.
