Problem 36BB

 

Sample Design Literacy In “Cardiovascular Effects of Intravenous Triiodothyronine in Patients Undergoing Coronary Artery Bypass Graft Surgery” (Journal of the American Medical Association, Vol. 275, No. 9), the authors explain that patients were assigned to one of three groups: (1) a group treated with triidothyronine, (2) a group treated with normal saline bolus and dopamine, and (3) a placebo group given normal saline. The authors summarize the sample design as a “prospective, randomized, double-blind, placebo-controlled trial.” Describe the meaning of each of those terms in the context of this study.

Step-by-Step Solution:
Step 1 of 3

Answer: 

Step1:  

            Given that, In “Cardiovascular Effects of Intravenous Triiodothyronine in Patients Undergoing Coronary Artery Bypass Graft Surgery”. the authors explain that patients were assigned to one of three groups: (1) a group treated with triiodothyronine, (2) a group treated with normal saline bolus and dopamine, and (3) a placebo group given normal saline.

   Here we have to describe the meaning of “prospective, randomized, double-blind, placebo-controlled trial.”

  • Prospective : The experiment was begun and results were followed forward in time.
  • Randomized: Subjects were assigned to the different groups through the process of random selection, and whereby they had the same chance of belonging to each group.
  • Double-blind: The subjects did not know which of the three groups they were in, and the people who evaluated results did not know either.
  • Placebo -controlled trial: There was a group of subjects who were given a placebo, by comparing the placebo group to the two treatment groups, the effect of the treatments might be better understood.
