Errors in “Methods” Section in: An Internally Controlled, Double-blind Comparison of the Efficacy of OnabotulinumtoxinA and AbobotulinumtoxinA

Arch Facial Plast Surg. 2012;14(2):140. doi:10.1001/archfacial.2012.1

Errors in “Methods” Section. In the article by Nettar et al titled “An Internally Controlled, Double-blind Comparison of the Efficacy of OnabotulinumtoxinA and AbobotulinumtoxinA,” published in the November/December issue of the journal (2011;13[6]:380-386), there were errors in the “Methods” section in the description of the product preparation and injection points. The fourth paragraph should have read:

“Treatment sides of the face were randomized with computer-aided software. Preparation of product was performed by an unblind registered nurse who was responsible for maintaining the blind. A 100-U vial of onabotulinumtoxinA was reconstituted with 2.0 mL of preservative-free, physiologic 0.9% saline. A 300-U vial of abobotulinumtoxinA was also reconstituted with 2.0 mL of preservative-free, physiologic 0.9% saline. Identical volumes (0.2 mL) of each were drawn into tuberculin syringes to ensure the blindedness of the injector. A dose of 0.05 mL of onabotulinumtoxinA or abobotulinumtoxinA was injected into the orbicularis oculi in the lateral orbital area in 4 separate injection points in aliquots of 0.05 mL (Figure 2) by the senior author and principal investigator (C.S.M.).”
