Risk of ischaemic stroke in people with migraine: systematic review and meta-analysis of observational studies

In our haste to correct this paper by Etminan and colleagues (BMJ 2005;330:63-5, 8 Jan), some of the authors' late corrections were not carried out properly—either at proof stage of the abridged print version or in the correction that we subsequently published on the web relating to the full version only. In the abridged version, the relative risk for migraine with aura in table 2 should be 2.88 (not 2.28); in table 1, the upper confidence limit for migraine with aura for Schwaag should be 3.53 (not 3.35), and the cases:controls for the Collaborative Group should be 430:151 (not 430:451). In the results section of the full version, the references for the data on migraine with and without aura are numbers 2, 3, 12-14, 17-19; in table 1, the cases:controls with migraine is 26:26 for Donaghy (not for Chang as stated in the previous correction).
