A randomized controlled trial investigated whether low-dose aspirin was beneficial in reducing the incidence of myocardial infarction. This study involved 16,000 participants and was randomly assigned to either low-dose aspirin or placebo pills. 8,000 study participants received low-dose aspirin and 8,000 received placebo pills. At the end of the study period, there were 450 cases of myocardial infarction in the low-dose aspirin group and 600 cases in the placebo group.
