Results from Cox proportional hazards models for time to renal replacement therapy (RRT) using time-varying assessment of recent angiotensin converting enzyme-I/angiotensin receptor blocker (ACE-I/ARB) use, unadjusted and adjusted for time-varying covariates and using inverse probability-of-treatment (IPT) weighting to assess the causal effect of continuous use of ACE-I/ARB.
