Study design Multi-center Double blinded RCT Population Characteristics of study participants 56.0% female N = 19114 44.0% male 19114 patients (10782 female, 8332 male) Inclusion criteria: adult healthy patients ( 65 years of age) without CVD, dementia, or disability Key exclusion criteria: history of a diagnosed CVD event, AF, serious illness likely to cause death within the next 5 years, current or recurrent condition with a high risk of major bleeding, uncontrolled BP, anemia, current use of aspirin for secondary prevention, or current continuous use of other antiplatelet drug or anticoagulant Interventions N=9525 aspirin (100 mg daily) N=9589 placebo (matching tablet) Primary outcome https://web.pathway.md/studies/recFFF5KBU9DI9fAS 1/2 6/28/23, 12:46 AM ASPREE Pathway Incidence of death from all causes 12.7/1000 py 12.7 11.1 9.5/1000 py 6.3/1000 py 3.2/1000 py Borderline significant increase 0.0/1000 py Aspirin Placebo Borderline significant increase in the incidence of death from all causes (12.7 /1000 py vs. 11.1 /1000 py; HR 1.14, 95% CI 1.01 to 1.29) Secondary outcomes Borderline significant increase in cancer-related death (3.1% vs. 2.3%; HR 1.31, 95% CI 1.1 to 1.56) No significant difference in death from CVD, including ischemic stroke (1% vs. 1.2%; HR 0.82, 95% CI 0.62 to 1.08) No significant difference in death from major hemorrhage, including hemorrhagic stroke (0.3% vs. 0.3%; HR 1.13, 95% CI 0.66 to 1.94) Conclusion In adult healthy patients ( 65 years of age) without CVD, dementia, or disability, aspirin was inferior to placebo with respect to the incidence of death from all causes.
