A systematic review and meta-analyses on the prevalence of pregnancy outcomes in migraine treated patients: a contribution from the IMI2 ConcePTION project.

The present study aims to summarize the safety profile of the medications used to treat migraine during pregnancy by performing a systematic review and meta-analyses. The term "migrain*" combined with pregnancy terms were used to search Embase, PubMed, PsychInfo, Scopus, and Web of Science through 31 December 2020. Pooled prevalences of untreated and treated migraine patients were estimated using MetaXL software. Pooled odds ratios (OR) using random effects models were estimated in RevMan 5. All the identified studies assessed medications used to treat acute migraine. The pooled prevalence of adverse pregnancy outcomes in patients prescribed any migraine medication ranged from 0.4% (95% CI 0.2-0.7%) for stillbirth to 12.0% (95%CI 7.8-16.9%) for spontaneous abortions. Among untreated patients with migraine, the pooled prevalence of the assessed pregnancy outcomes ranged from 0.6% (95% CI: 0-1.7%) for stillbirth to 10.4% (95% CI: 8.9-12%) for gestational age
