An experiment tested the ability of maggots to remove dead tissue from open wounds that would not heal on their own. Sterile maggots were placed in a small pouch which, in turn, was placed on the wound. 80 women with wounds on their lower limbs were randomly assigned to receive either a traditional surgical treatment or maggot therapy. After eight days, the percentage of dead tissue in the wounds that underwent maggot treatment was 53.7%, compared to 66.6% with the surgical treatment. Neither patients nor the doctors evaluating the wounds knew which therapy had been applied. (Patients were blindfolded as bandages were changed.) Surprisingly, the number of patients that reported a crawling sensation in their wound was about the same in both groups! Complete parts a through d below. a) What kind of study was this?

Question
An experiment tested the ability of maggots to remove dead tissue from open wounds that would not heal on their own. Sterile maggots were placed in a small pouch which, in turn, was placed on the wound. 80 women with wounds on their lower limbs were randomly assigned to receive either a traditional surgical treatment or maggot therapy. After eight days, the percentage of dead tissue in the wounds that underwent maggot treatment was 53.7%, compared to 66.6% with the surgical treatment. Neither patients nor the doctors evaluating the wounds knew which therapy had been applied. (Patients were blindfolded as bandages were changed.) Surprisingly, the number of patients that reported a crawling sensation in their wound was about the same in both groups! Complete parts a through d below. b) Is that an appropriate choice for this investigation? O A. Yes, such an experiment is an appropriate way to determine whether maggots were as effective as surgery. O B. Yes, because all studies should be done that way. O C. No, because the study should be observational. O D. No, because there should already be plenty of past data on this issue available.
