Notes: Difference/Std. Dev is the difference divided by the standard deviation if the variable is continuous. If it is a dichotomous variable, then this column reports the difference divided by the sample mean.

1. Average total charges for surgery patients are for patients without a complication and who are not part of the analyses.
