^a HR Hazard ratio, ^b: Confidence interval, ^c: cART Combined anti-retroviral treatment
Basic models are adjusted for age, and final models are adjusted for age and all predictors with a p value < 0.1 in the basic models (diabetes, absence of c-ART at dialysis initiation)
Values in bold are significant (p < 0.05)
