Textbook Question
Chapter 1, Problem 5CT
Researchers studied 393 patients in a hospital’s coronary care unit. In the experiment, volunteers were asked to pray daily for a patient’s rapid recovery and for the prevention of complications and death.
None of the patients knew if he or she was being prayed for. None of the volunteers or patients knew each other. The research team categorized how each patient fared as “good,” “intermediate,” or “bad.” They concluded that “prayed for” patients fared a little better than other patients—the experiment having documented results that seemed to support the prediction that prayer might have beneficial effects for seriously ill patients.
The results brought a storm of criticism, mostly from scientists who cited bias in the experimental design. For instance, the patients were categorized after the experiment was over, instead of as they were undergoing treatment, so the team already knew which ones had improved, stayed about the same, or gotten worse. Why do you suppose the experiment generated a heated response from many in the scientific community? Can you think of at least one other variable that might have affected the outcome of each patient’s illness?

The following case study is a paraphrase from "Good Clinical Practice. Standard Operating Procedures for Clinical Researchers" (Kolman, J., Meng, P. and Scott, G. editors; John Wiley and Sons publishers, 1998):
“While a study subject and a relative were walking in town one day during the summer, a hanging flower basket fell on a study subjects head, resulting in the study subject falling down and becoming unconscious. The subject’s relative called for an ambulance. On arrival at a local hospital’s Emergency Department, in which the subject regained consciousness but could not recall the event, a x-ray revealed a fractured skull. The subject’s consciousness level at this point was deteriorating and after further tests a subdural hematoma was diagnosed, which was evacuated under general anesthesia. Postoperative recovery was uneventful and progressing well until day four, when the patient developed acute dyspnea (shortness of breath) at rest during visiting time. An emergency lung scan…

Which of the following descriptions most closely describes the control used in this study? Show answer choices The researcher has organized the patients into 4 groups, where patients either take 1 dose of the drug, 2 doses of the drug, 1 dose of the placebo, or 2 doses of the placebo. The physician asks patients to rate their heartburn discomfort on a scale from 1-10 every 5 minutes up to an hour. The physician and patients both do not know if they are receiving the actual drug or a placebo. The placebo pill contains just compressed sugar and no active drug. Patients are randomly selected and placed into the four categories.arrow_forwardhe first involved an assessment of the relationship between cigarette smoking and incidence of lung cancer. For cigarette smokers, the lung cancer incidence rate was Ie = 200 per 100,000. For nonsmokers, the lung cancer incidence rate was Io = 25 per 100,000. The lung cancer incidence rate in the entire population was It = 100 per 100,000. The second study involved an assessment of the relationship between cigarette smoking and incidence of coronary heart disease. For cigarette smokers, the coronary heart disease incidence rate was Ie = 500 per 100,000. For nonsmokers, it was Io = 250 per 100,000. In the overall population, the coronary heart disease rate was It = 300. 1.
