So I recently received a comment from one of the reviewer which states as below:
"As evidenced by the differences in baseline characteristics, there is certainly residual confounding between the patients who underwent leukapheresis and those who did not. Reporting HR for leukapheresis vs no leukapheresis without matching
for those confounders is inappropriate or at least severely limited in my opinion."
Is there a method to conduct kaplan-meier curve with confounders matching in SPSS? Cause in SPSS, it appears the curve can only be made with one variable.
Many thanks for the help

Add confounder to the regression equation and then see our attached paper. D.Booth
