The graph shows a secondary analysis of data from 1992 to 2014 on 4371 women with type 2 diabetes in the E3N Cohort Study. The prevalences of migraine and their 95% CIs have been estimated from a generalized estimating equations model from 24 years prior to 22 years after type 2 diabetes diagnosis. Year 0 is the date of type 2 diagnosis. Models were adjusted for age, level of education, family history of diabetes, body mass index, smoking status, hypertension, level of recreational physical activity, use of oral contraceptives, menopausal status, menopausal hormone therapy use, and handedness.
