Step 1
The question refers to a forest plot from a meta-analysis examining the effect of statins on the risk of death and acute coronary syndromes in patients undergoing cardiac surgery. A specific study within this meta-analysis, conducted by Ali and Bluth in 2005, Show more…

Preventing strokes Aspirin prevents blood from clotting and so helps prevent strokes. The Second European Stroke Prevention Study asked whether adding another anticlotting drug named dipyridamole would be more effective for patients who had already had a stroke. Here are the data on strokes during the two years of the study:22 (a) Summarize these data in a two-way table. (b) Make a graph to compare the rates of strokes for the four treatments. Describe what you see. (c) Explain in words what the null hypothesis $H_{0} :$ $p_{1}=p_{2}=p_{3}=p_{4}$ says about the incidence of strokes. (d) Find the expected counts if $H_{0}$ is true, and display them in a two-way table similar to the table of observed counts.

Physician's Health Study In the Physician's Health Study, introduced in Data 1.6 on page 37, 22,071 male physicians participated in a study to determine whether taking a daily low-dose aspirin reduced the risk of heart attacks. The men were randomly assigned to two groups and the study was double-blind. After five years, 104 of the 11,037 men taking a daily low-dose aspirin had had a heart attack while 189 of the 11,034 men taking a placebo had had a heart attack. $^{52}$ Does taking a daily low-dose aspirin reduce the risk of heart attacks? Conduct the test, and, in addition, explain why we can infer a causal relationship from the results.

Test for a Difference in Proportions
Preventing strokes Aspirin prevents blood from clotting and so helps prevent strokes. The Second European Stroke Prevention Study asked whether adding another anticlotting drug, named dipyridamole, would be more effective for patients who had already had a stroke. Here are the data on strokes and deaths during the two years of the study:$^{16}$ $$\begin{array}{ll} &{\text { Number of }} & {\text { Number of }} \\ & {\text { patients }} & {\text { strokes }} \\ \hline \text {Aspirin alone } & 1649 & {206} \\ \text {Aspirin + dipyridamole }& {1650} & {157}\end{array}$$ The study was a randomized comparative experiment. (a) Is there a significant difference in the proportion of strokes between these two treatments? Carry out an appropriate test to help answer this question. (b) Describe a Type I and a Type II error in this setting. Which is more serious? Explain.
