Question

I know the answer but I can't interpret it

Risk difference

189/11,034 – 104/11,037

= 0.0171 − 0.0094

= 0.0077 or 0.77%

Interpretation(s):

0.77% (absolute) to ____ in placebo group as compared to aspirin group.
0.77% --- about risk

A prospective study on the relationship between aspirin use and heart attacks by the Physicians'
Health Study Research Group at Harvard Medical School is presented below. The Physicians
Health Study was a 5-year randomized study of whether regular aspirin intake reduces risk of
myocardial infarction or heart attack. Every other day, physicians participating in the study took
either one aspirin tablet or a placebo. The study was blind - those in the study did not know whether
they were taking aspirin or aplacebo.
Of the 11,034 physicians taking a placebo, 189 suffered heart attacks over the course of the
study, whereas of the 11,037 taking aspirin, 104 had heart attacks. Can we say that the intake of
aspirin appears to diminish the risk of myocardial infarction?
