IRR: Incidence Rate Ratios calculated using multivariate Poisson regression.

OR: Odds Ratio calculated using logistic regression models.

The logistic regression multivariate model and Poisson regression model were built using as dependent variables “death (yes/no)” and “Cumulative incidence of PCI” respectively, and as independent variables year, sex, Charlson comorbidity index, and age.
