dataKTFS: A Sixth Sample Of The DIVAT Cohort.

In RISCA: Causal Inference and Prediction in Cohort-Based Analyses

A Sixth 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 for the 3 following variables:

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.
