Figure 1. Diagram of Patient Flow in the Analysis.

Participants were randomly assigned to aspirin dose but not to aspirin formulation, which was at the discretion of the participant. For several analyses, participants were grouped by aspirin formulation regardless of aspirin dose (shown at the bottom of the figure). Regardless of aspirin dose, there were 7366 total participants taking enteric-coated aspirin and 3312 taking uncoated aspirin.
