Description Usage Format Source References


These data sets give the times (in years) from HIV infection to AIDS, SI switch and death in 329 men who have sex with men (MSM). Data are from the period until combination anti-retroviral therapy became available (1996). For more background information on the cohort, ccr5 and SI, see Geskus et al. (2000, 2003)

aidssi contains follow-up data until the first of AIDS and SI switch. It was used as example for the competing risks analyses in Putter, Fiocco, Geskus (2007) and in Geskus (2016).
