I am new at using survival analyses. I am writing an article on differences in recidivism for an experimental and control group of offenders. Due to differences between the groups in gender, I have added gender as covariate to my Cox Regression analysis. In Kaplan Meier, I get the mean survival time (no median, I think because in one of the groups the hazard ratio does not reach $0.50$), but this analysis does not take the covariate into consideration. Is it possible to request the mean survival time in Cox Regression using SPSS, for the analysis including the covariate?
