I need to stratify medians by the outcome and get the percentiles, what is the syntax for this? I have a term "weight" which is a continuous variable Outcome is categorical (treatment/no treatment) Weight is not normally distributed I wanted to make a table with the median weight of tissue for those who received treatment and those who did not...
