Format

A data frame of 2279 patients transplanted at the EBMT between 1985 and 1998. These data were used in Fiocco, Putter & van Houwelingen (2008) and van Houwelingen & Putter (2008). The included variables are

id: Patient identification number
rec: Time in days from transplantation to recovery or last follow-up
rec.s: Recovery status; 1 = recovery, 0 = censored
ae: Time in days from transplantation to adverse event (AE) or last follow-up
ae.s: Adverse event status; 1 = adverse event, 0 = censored
recae: Time in days from transplantation to both recovery and AE or last follow-up
plag.s: Recovery and AE status; 1 = both recovery and AE, 0 = no recovery or no AE or censored
rel: Time in days from transplantation to relapse or last follow-up
rel.s: Relapse status; 1 = relapse, 0 = censored
srv: Time in days from transplantation to death or last follow-up
srv.s: Relapse status; 1 = dead, 0 = censored
year: Year of transplantation; factor with levels "1985-1989", "1990-1994", "1995-1998"
agecl: Patient age at transplant; factor with levels "<=20", "20-40",="" "="">40"
proph: Prophylaxis; factor with levels "no", "yes"
match: Donor-recipient gender match; factor with levels "no gender mismatch", "gender mismatch"
