Bone Marrow Transplant

Description

Bone marrow transplant data from L Scrucca et aL., Bone Marrow Transplantation (2007). Data from 35 patients with acute leukaemia who underwent HSCT. Used for competing risk analysis.

Usage

data("BMT")

Format

A data frame with 35 rows and 3 columns.

- dis: disease; 0 = ALL; 1 = AML
- ftime: follow-up time
- status: 0 = censored (survival); 1 = Transplant-related mortality; 2 = relapse
