For their study, researchers looked at data from more than 19,114 patients from Aspree, a trial that assigned 9,525 patients to treatment with aspirin, while 9,589 received a placebo.
The study identified age, smoking, chronic kidney disease as risk factors for upper gastrointestinal bleeding.
The risk of lower gastrointestinal bleeding, on the other hand, was linked to age, smoking and hypertension.
The team found that the absolute, five-year serious bleeding risk was 0.2 recent for individuals, based on the results.
