163 Migraine attack incidence in relation to ovulation 7 Table e-4. Results of mixed logistic regression model in the complete case analyses where patients with chronic migraine are added (n = 100) to the LHC cohort (n=554), resulting in a group of 654 patients with recordings of 2927 menstrual cycles. Migraine attack is the dependent variable in the model, and ovulatory window and perimenstrual window as fixed effects and the patient as random effect.
