Migraine is the second most prevalent neurological disorder. The potential causal relationship between PFO and migraine has been a subject of ongoing debate. This study aims to investigate the genetic association between PFO and migraine.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and methods<\/jats:title>\n                    <jats:p>This study utilized aggregated data from the Finnish database to explore the genetic causal relationship between PFO as an exposure factor and migraine as an outcome factor. We employed a MR design, with inverse variance weighting (IVW) as the primary analysis method, supplemented by MR-Egger regression.
