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 1 df, p=0.140 ?n= 467 I wanna extract the result: 0.216 ? ? ?1.24 ? ?0.146 1.47 0.14 and the corresponding name "coef exp(coef) se(coef) ? ?z ? ?p" from fit_cox. I use the command: str(fit_cox),but I can only find 0.216 of the result,but the other four results( 1.24 ? ?0.146 1.47 0.14) can't be found. Anyone can help me? Thanks a lot!
