    Summary · context
    While glucagon-like peptide-1 receptor agonists (GLP-1 RAs) lower body mass index (BMI) in youths with obesity, less is known about their effect on metabolic parameters such as alanine aminotransferase (ALT), high-density lipoprotein, low-density lipoprotein, and hemoglobin A1c levels.
