The original publication has been corrected. The incorrect and correct figure legends are presented below.

• Corrected Figure 3 legend:
≥1-Point Reduction in Pain Intensity at 30, 60, and 120 Minutes for (a) First Attack and (b) All Attacks. Models are adjusted for the patients’ baseline pain score, use of preventive therapies, and presence of aura; data for number of patients are unadjusted numbers. Abbreviation: nVNS, non-invasive vagus nerve stimulation
