Research suggests that aspirin can reduce the chance of future heart attacks for heart attack sufferers. Researchers compare the heart stress score for people taking aspirin after a heart attack and people taking nothing after a heart attack. Although the groups are separate people (because you can't take and not take aspirin), the researchers match the groups for age, gender, socioeconomic status and BMI (things that can impact heart stress). We obtain the heart stress scores seen below (higher scores indicate greater heart stress). Does aspirin impact heart stress? Test at = .01.
