Description

A dataset containing survival outcome and predictors on 694 patients who received hematopoietic stem cell transplant.

Usage

1

Format

A data frame with 694 rows and 11 variables. Each row describes the data from a single patient. The below described variables are included in the data file. Missing observations are present in the variables performance status(9%), remission status (6%) and cytogenic abnormality (25%).

id

record identification number

age10

age at transplantation

perfstat

performance status indicated by the Karnofsky Index (four categories)

remstat

remission status at transplantation (three categories)

cyto

cytogenetic abnormalities (four categories)

asct

previous autologous transplantation (two categories)

donor

donor type (three categories)

sex_match

patient-donor sex match (four categories)

cond

conditioning regimen (three categories)

srv5y

overall survival (OS) up to five years after first allogeneic stem cell transplantation

srv5y_s

censoring indicator (0=alive at end follow-up, 1=dead)
