Nutritional supplements for migraine prevention: evaluating evidence sufficiency and effect modifiers through network meta-analysis, trial sequential analysis, and meta-regression.

This research looked at how well nutritional supplements can prevent migraines. The study used advanced methods to compare different supplements based on their effectiveness and safety. Researchers gathered data from randomized controlled trials involving adults with migraines. They focused on key outcomes like migraine frequency, duration, and severity, while also noting any side effects. The analysis calculated average differences in outcomes and the likelihood of adverse events. Results were ranked to see which supplements worked best, although these rankings were considered exploratory. The study also investigated variations in results across different studies. Overall, the findings suggest that some nutritional supplements may help with migraine prevention, but more research is needed to confirm these benefits and understand how various factors might influence effectiveness. Clinical relevance: This research indicates that certain nutritional supplements could be beneficial for migraine prevention, providing patients and clinicians with potential new options for managing this condition.
