Unfortunately, I am unable to produce an abstract of the requested article because the search results provided do not include the article titled "GLP-1 Agents Tied to Less Risk of Asthma Exacerbations in Teens With Obesity" from MedPage Today. The available search results contain information on the use of GLP-1 analogues (especially liraglutide) in the treatment of obesity in adolescents, but do not contain data on the effect of these agents on asthma exacerbations. In order to produce an accurate and factual summary, I would need access to the full text of the article in question.
