The Study
Daily aspirin for primary prevention increased risk for major GI bleeding in healthy older adults
This study gave some older people aspirin and others a placebo to see what happened. It found that those taking aspirin had more stomach bleeding, so it's likely aspirin caused it — but we’re not 100% sure because we don’t know if everyone was blinded.
