  1. MI myocardial infarction, TVR target vessel revascularisation, MACE major adverse cardiac events (death/MI/TVR). * Number of events are counts, and percent in parentheses is the unadjusted one-year risk (survival probability calculated from the Kaplan-Meier estimate at 1 year. P-value is from log-rank test across years).
  2. ** Adjusted one-year risk (%) is the survival probability calculated from the fitted multivariate Cox model for 2000-2004 that includes calendar year, age, Charlson score, gender, index principal discharge diagnosis, type of index admission, type of hospital, number of vessels treated and type of CARP (only for All CARPs data). P-value is from Type 3 Wald test for calendar year from the fitted Cox model.
