RISCA (version 0.8)

dataKTFS: A Fifth Sample Of The DIVAT Cohort.

Description

A data frame with 2169 French kidney transplant recipients for who the Kidney Transplant Failure Score (KTFS) was collected. The KTFS is a score proposed by Foucher et al. (2010) to stratify the recipients according to their risk of return in dialysis.

Usage

data(dataKTFS)

Format

A data frame with 2169 observations (raws) with the 3 following variables (columns).

time

This numeric vector represents the follow up time in years (until return in dialyis or censoring)

failure

This numeric vector represents the graft failure indicator at the follow-up end (1=return, 0=censoring)

score

This numeric vector represents the KTFS values.
