Could you give us an example of what exactly you are doing
(preferablly reproducible R code)? I may be misunderstanding you, but
if you are fitting cox proportional hazard models using the coxph()
function from the surival package, summary(yourmodel) should give the
SE, p-value based on the wald statistic, and 95% CI.
