Question

Avandia is an anti-diabetic drug and, like all drugs, it can have side effects. One study of patients with congestive heart failure found that 5 of the 110 subjects randomly assigned to Avandia dies of a cardiovascular event during the duration of the study, compared with 4 of the 114 subjects assigned to the placebo. Is there evidence that patients with congestive heart failure have a higher probability of dying of a cardiovascular event if they take Avandia than if they take a placebo?
