Dr. Bennett believes thаt а newly synthesized cоmpоund, Xylоzine, mаy be effective in reducing the severity of symptoms in patients with seasonal allergies. Preliminary tests in the lab have shown that Xylozine can counteract the effects of certain allergens. Dr. Bennett's clinic has a diverse group of patients with varying levels of seasonal allergy severity. He also has access to a placebo that is indistinguishable from Xylozine in appearance and taste. Given Dr. Bennett’s goal and the fact that he can supply patients with either Xylozine or a look-alike placebo, which study design would generate the cleanest evidence for the drug’s effectiveness? [1] Why is it essential that neither the participants nor the clinic staff know who receives Xylozine versus placebo in the study you design? [2] Imagine some participants begin taking over-the-counter antihistamines during the trial without telling the research team. According to the “dirty data” categories in the handout, which problem does this introduce? [3] If Dr. Bennett reviews the symptom diaries and pays more attention to participants who report improvement while overlooking those who do not, which “dirty data” category from the handout is most likely at play? [4] Which specific feature of the proposed study is designed to protect the results from being distorted by the placebo effect? [5] After the study, a marketing brochure quotes two participants who claimed Xylozine “changed my life” and ignores the majority who reported little difference. Which dirty-data category best describes this selective storytelling? [6]
