Notes.
a
Binary data are presented as no./total no. (%), continuous data as medians (25th–75th percentile), means for predicted mortality.
b
Odds ratio for binary variables and estimated median difference for continuous variables, mean difference for predicted mortality.
c
Differences between survivors and non-survivors assessed with Fisher’s exact test for binary variables and the Wilcoxon rank sum test for continuous variables, the Welch two sample T test for predicted mortality.
d
For one survivor the exact age in months is not known.
