Stigma towards people with migraine among respondents who felt impacted (“Yes”) by having a family member with migraine (A) and a co-worker/supervisor/employee with migraine (B) vs. those who did not feel impacted (“No”). Standardized mean differences were used to determine comparisons between those who indicated they felt impacted by having a coworker/supervisor/employee or family member with migraine (“Yes”) vs. those who did not feel impacted (“No”). SMD values < 0.2 were considered not different, * indicates a small difference (SMD = 0.2–0.49), ** a moderate difference (SMD = 0.5–0.79), and *** a large difference (SMD ≥ 0.8)
