I found some information about using 'proc causaltrt' procedure such as IPWS to calculate ATT (SAS code below from https://documentation.sas.com/doc/en/statcdc/14.2/statug/statug_causaltrt_examples01.htm). However, I am not sure how to get survival outcomes using this procedure. I can find some R packages for this purpose. Could you help me figure it out using SAS? Many thanks.

Are you trying to get something like an IPT-weighted hazard ratio?
Yes, kind of. Could you help me figure it out? Many thanks.
