wihs: Women's Interagency HIV Study (WIHS)

In ehrlinger/randomForestSRC: Random Forests for Survival, Regression and Classification (RF-SRC)

Description

Competing risk data set involving AIDS in women.

Format

A data frame containing:

time	time to event
status	censoring status: 0=censoring, 1=HAART initiation, 2=AIDS/Death before HAART
ageatfda	age in years at time of FDA approval of first protease inhibitor
idu	history of IDU: 0=no history, 1=history
black	race: 0=not African-American; 1=African-American
cd4nadir	CD4 count (per 100 cells/ul)

Study included 1164 women enrolled in WIHS, who were alive, infected with HIV, and free of clinical AIDS on December, 1995, when the first protease inhibitor (saquinavir mesylate) was approved by the Federal Drug Administration. Women were followed until the first of the following occurred: treatment initiation, AIDS diagnosis, death, or administrative censoring (September, 2006). Variables included history of injection drug use at WIHS enrollment, whether an individual was African American, age, and CD4 nadir prior to baseline.
