Error in Methods

In the Original Investigation titled “Comparison of Botulinum Toxin A Formulations for Glabellar Strain Treatment in Women: A Double-Blind Randomized Clinical Trial,”¹ published online on May 28, 2025, and in the July 2025 issue, there was an error in the Methods section. The sentence “All reconstitutions were performed with 2.5 mL of sterile saline solution per a 100-unit or 300-unit (ABoNT/A) vial, and all treatments were performed with 0.2 mL of product” should be “Reconstitutions were performed with 2.5 mL of sterile saline per 100 units (OBoNT/A, PBoNT/A, IBoNT/A) or 3.0 mL per 300 unit (ABoNT/A) vial and each injection point was treated with 0.1 mL of product,” and in the previous sentence, “60 units” should be “50 units.” This article was corrected online.
