^aβ (95% CI): beta coefficient and corresponding 95% confidence intervals. Model 1 analysis was adjusted for gender. Model 2 analysis was additionally adjusted for migraine duration and migraine frequency. Model 3 analysis was additionally adjusted for other migraine characteristics
^bP for interaction
