Should variables used in PROC PSMATCH (or PROC LOGISTIC prior to PSMATCH) be re-used in the outcome analysis?   For example, if we match on gender, should we use gender in the outcome analysis? Here are the imagined steps:   1. Calculate the propensity score with gender as a variable (e.g., treated = gender) in PROC LOGISTIC or PSMATCH 2. Match on gender with PSMATCH 3. Run the outcome analysis with PROC UNIVARIATE using gender in the model   See this for example:   https://documentation.sas.com/?docsetId=statug&docsetTarget=statug_psmatch_examples05.htm&docsetVersion=14.3&locale=en   Why should gender be in the final analysis?
