Question

The Physicians' Health Study randomly assigned 22,071 healthy male physicians at least 40 years old to take either an aspirin every other day or a placebo pill every other day. Of the 11574 physicians who took aspirin regularly for 5 years, 5 had a fatal heart attack and 126 had a nonfatal heart attack. Of the 10497 who took the placebo, 21 suffered a fatal heart attack and 216 had a nonfatal heart attack. Please use 4 decimal places to answer the questions below. (a) What is the proportion of physicians who suffered a fatal heart attack in the: aspirin group?| placebo group? (b) Calculate the relative risk of a fatal heart attack for physicians taking aspirin compared with those taking a placebo (do not use the rounded values from part (a) to do your calculations, Use the original proportions in your calculation. Remember, give your answer to 4 decimal places.). (c) What is the proportion of physicians who suffered a nonfatal heart attack in the: aspirin group? placebo group? id) Calculate the relative risk of a nonfatal heart attack, for physicians taking aspirin compared with those taking a placebo (do not use rounded values in your calculation and give your answer to 4 decimal places).

Explanation / Answer

a)

Aspirin=5/11574=0.000432

Placebo=21/10497=0.00200057

b)

0.000432/0.00200057=0.2159 (Means it is only 21.59% of those taking placebo)

c)

Aspirin=126/11574=0.010886

Placebo=216/10497=0.020577

d)

0.010886/0.020577=0.5290 (Means it is only 52.9% of those taking placebo)
