(b) A placebo is a fake treatment designed to resemble an actual treatment (all four treatments were administered via subcutaneous injections). Did any of the active treatments perform better than the placebo? 0 One active treatment performed better than the placebo. 0 Two of the active treatments performed better than the placebo. 0 All of the active treatments performed better than the placebo. 0 None of the active treatments performed better than the placebo. Why is it important to compare the results from the active treatments with the results when a placebo is administered? 0 If the placebo performs better than an active treatment, it means the trial was a failure. 0 Because the psychological impact of undergoing treatment can be measured by the placebo. O The placebo results tell us if any of the patients were not sick enough to be in the trial. 0 The results of the placebo treatment make the results of the active treatments look better by comparison. (c) Compare the percent of patients showing no more symptoms for each of the three active treatment groups. Was one active treatment more effective than the others in this study? 0 The active treatments all performed about the same. 0 Ustekinumab performed than the rest of the active treatments. 0 Brodulamab, low dose, performed better than the rest of the active treatments. 0 Brodularnab, high dose, performed better than the rest of the active treatments.
