help: calculations for causespecific hazard ratios in a competing risks analysis with timedependent covariates
Dear R users:
Analysis of the impact of a time-dependent covariate (GVHD or use of steroid after bone marrow transplantation) on two competing endpoints (invasive fungal infection and death) is frequently encountered in the setting of BMT data. Coxph package can be used as the following:
for the analysis of GVHD:
> gvhd -> coxph(Surv(start,stop,status = =1) ~ GVHD, data=bmt.data)
