Kaplan‐Meier curves and standard Cox proportional‐hazard regression models with baseline time‐fixed covariates were used to compare the time to developing a new AIDS or serious non‐AIDS events (SNAEs) diagnosis (cardiovascular disease, non‐AIDS cancer, end‐stage liver disease and end‐stage renal disease) or death after baseline according to CD4 count response groups. Here, CD4 is linked to AIDS.
