PART 4 Based on your results in part (4.3), make a decision linked in context. Cardiac Study PART 1 In a clinical trial to compare the effectiveness of two drugs in preventing heart attacks, 25,620 patients were randomly divided into three groups. One group took a tablet of drug A each day. The next group took a table of drug B each day. The third group took one table of each drug each day. Patients were studied for 56 months and the number of who suffered heart attacks (fatal and non-fatal) were counted.
