This figure demonstrates the effectiveness of Inverse Probability Weighting adjustment. Bleeding risks cohorts: total – Figure 3A, low – Figure 3B, intermediate – Figure 3C, high – Figure 3D. The effectiveness of the IPW was evaluated using Cramer’s Phi (V) and R-squared and displayed graphically; values closer to zero demonstrate a more balanced cohort. Abbreviations: IPW – inverse probability weighting. PCI – percutaneous coronary intervention. MI – myocardial infarction. CHF – congestive heart failure. NYHA – New York Hospital Association. CAD – coronary artery disease.
