Write answer in between .Q:A medical research study is evaluating an investigational novel drug medication 1 as compared with standard therapy medication 2 in patients presenting to the emergency department with myocardial infarction MI. The study enrolled a total of 3,000 subjects, 1,500 in each study arm. Follow-up was conducted at 45 days post-MI. The following are the results of the trial:Endpoints Medication 1 Medication 2 P-ValuePrimary: death from cardiac causes 134 210 0.03Secondary: hyperkalemia 57 70 0.4What is the relative risk of death from a cardiac cause? Round to the nearest whole number.? A: 36, B: 42, C: 57, D: 64, E: 72,  <response>: This is a question about calculating relative risk from a medical research study comparing two treatments. The results show the number of patients in each arm who died from cardiac causes and the p-value. To calculate relative risk, we take the incidence rate in the treatment group medication 1 divided by the incidence rate in the control group medication 2.The incidence rate for medication 1 is 1341500 0.089. The incidence rate for medication 2 is 2101500 0.14.So the relative risk is 0.0890.14 0.64.D: 64
