Most of these exercises pose issues for discussion. There are no right or wrong answers, but there are more and less thoughtful answers.

Question 3.79

3.79 The Vytorin controversy.

Vytorin is a combination pill designed to lower cholesterol. The combination consists of a relatively inexpensive and widely used drug, Zocor, and a newer drug called Zetia. Early study results suggested that Vytorin was no more effective than Zetia. Critics claimed that the makers of the drugs tried to change the response variable for the study, and two congressional panels investigated why there was a two-year delay in the release of the results. Use the Web to search for more information about this controversy, and write a report of what you find. Include an evaluation in the framework of ethical use of experiments and data. A good place to start your search would be to look for the phrase “Vytorin’s shortcomings.”
