about the cox result
Hi all:
I finished cox analysis like this:
fit_cox<-coxph(Surv(dat$Time, dat$death) ~ dat$CD4 + strata(dat$gender),data=dat);
> fit_cox
Call:
coxph(formula = Surv(data_ori$Time, data_ori$death) ~ data_ori$drug +
strata(data_ori$gender), data = data_ori)
coef exp(coef) se(coef) z p
data_ori$drugddI 0.216 1.24 0.146 1.47 0.14
Likelihood ratio test=2.17 on
