A randomized clinical trial compared aspirin to placebo for the prevention of heart attacks (MIs) and strokes. Out of a total of 1,000 subjects on aspirin, there were 80 heart attacks and 65 strokes; out of a total of 2,000 subjects on placebo, there were 240 heart attacks and 165 strokes. is there a significant benefit for aspirin therapy for heart attacks and strokes? What is the RR for aspirin use for each of these two outcomes? (Careful here, you are given the total number of subjects in each group and the number of complications.)
