The questionnaire established a headache profile, which was designed to comply with the second edition of the International Classification of Headache Disorders (ICHD-2). We investigated severity of headache based on effect of daily activity (mild, moderate and severe) and using visual analogue scale. Migraine was diagnosed based on the ICHD-2 criteria for migraine without aura (code 1.1) [31]. We did not attempt to separately diagnose migraine with aura and migraine without aura. As such, both were included in the present study. The questions used to diagnose migraine were previously found to have 75.0 % sensitivity and 88.2 % specificity, by comparing the diagnoses from the survey with doctors’ diagnoses obtained from an additional telephone interview. The validation process was described in one of author’s (MKC) previous article in detail [3]."}
