Migraine served as primary outcome variable and was stringently defined as a diagnosis from specialised health care and\/or \u22652 reimbursed purchases of triptans. We applied sex- and birth year-stratified Cox proportional hazard regression models to compute hazard ratios and confidence intervals (95% confidence intervals) for the association between preterm categories and migraine.

The corresponding adjusted hazard ratios and 95% confidence intervals for the other preterm categories were: Very preterm (28\u201331 weeks); 0.95 (0.68\u20131.31), moderately preterm (32\u201333 weeks); 0.96 (0.73\u20131.27), late preterm (34\u201336 weeks); 1.01 (0.91\u20131.11), early term (37\u201338 weeks); 0.98 (0.93\u20131.03), and post term (42 weeks); 0.98 (0.89\u20131.08).
