Hi, I am wondering if anyone can explain to me if cumulative incidence (CI) is
just "1 minus kaplan-Meier survival"? Under what circumstance, you should use
cumulative incidence vs KM survival? If the relationship is just CI =
1-survival, then what difference it makes to use one vs. the other?
And in R how I can draw a cumulative incidence plot. I know I can make a
Kaplan-Meier survival plot using plot(survfit()), for example:
fit<-survfit(Surv(time,status)~group,data=data)
plot(fit, col=1:2)
How to draw CI plot then?
Thanks very much!
John
