A study investigated the effectiveness of a new statin therapy in preventing ischaemic heart disease in a diabetic population. Over a period of five years, 1000 patients were randomly assigned to receive the new therapy and 1000 were given a placebo. The placebo group experienced 150 myocardial infarctions (MIs), while the group treated with the new statin had 100 infarctions. What is the yearly percentage of MIs in the diabetic population who received the placebo?

In a study of the treatment of middle-aged patients with atrial fibrillation, the results showed that those who received warfarin had a 6% incidence of stroke or stroke-related death over a three-year period. Those treated with aspirin had a 9% incidence, while the untreated group had a 12% incidence. What is the estimated annual incidence of stroke in the treated population in this study?

A study examines the effectiveness of a new antiplatelet agent versus aspirin in preventing stroke in a diabetic population over a ten year period. The results show that the incidence of stroke in the aspirin treated group is 6%, while the group treated with the new drug has a rate of 3% (p <0.001). What is the relative risk reduction in stroke associated with the new medication?
