Correction

Following the publication of this article [1], the authors noticed that they incorrectly reported the Absolute risk of ischemic stroke in women aged 20 to 44 years in relation to the use of hormonal contraception and migraine status due to a miscalculation. They apologize for this misreported result.

The correct version of Table 4 has been included in this correction.

Table 4 (Revised) Absolute risk of ischemic stroke in women aged 20 to 44 years in relation to the use of hormonal contraception and migraine status
