*
N is the number of non–missing values. Numbers after percents are frequencies.
†
The P values evaluate whether the variable ispredictive of a more “severe” outcome.
‡
For each of these variables, the three numbers given represent the lower quartile, the median, and the upper quartile for continuous variables.
