Hi All,
This sounds a relatively simple query, and I hope it is!
I am looking at a continuous variable, age. I am looking at time to
12-month remission and can calculate the HR and 95% confidence interval are
follows:
coxfita = coxph(Surv(rem.Remtime,rem.Rcens)~nearma$all.age,data=nearma)
exp(coxfita$coefficients)
exp(confint(coxfita))
However, because I am looking at age as a continuous variable I cannot draw
a Kaplan-Meier curve. Instead I need to draw a plot of hazard against age.
How do I do this? I don't think
plot(nearma$all.age,coxfita$linear.predictors) is quite right.
Thank you for your help,
Laura
