What kind of article is the following abstract from: The study compared the efficacy and safety of various biologics in the management of chronic rhinosinusitis with nasal polyps. The PubMed, Cochrane Library, and Web of Science databases were searched. Two independent reviewers screened the studies, extracted the data, and performed a quality assessment using the Cochrane Risk of Bias tool. Ten placebo-controlled RCTs were included comparing 4 biologics. Dupilumab demonstrated superior long-term efficacy compared to the other 3 biologics. Dupilumab showed improvements in the Nasal Polyp Score of 1.84 (95% CI 0.78, 2.91) compared to mepolizumab and 2.31 (95% CI 0.99, 3.63) compared to benralizumab.
