In the version of the article, “Patent Foramen Ovale and Migraine: A Cross-Sectional Study From the Northern Manhattan Study (NOMAS),” by Rundek et al that was posted online on September 15, 2008 (DOI: 10.1161/CIRCULATIONAHA.108.771303), an error occurred.
In the Clinical Perspective, the phrase, “and 2% of individuals with migraine had PFO,” should read, “and 2% of all individuals had migraine and PFO.”
The error has been corrected in the final print version of the article in the September 30, 2008, issue of the journal (Circulation. 2008;118:1419–1424) and in the current online version.
The authors regret the error.
