- Values are based on n (%). χ2 test for qualitative data have been used. aThe VAS score was for mild pain [1,2,3], moderate pain [4,5,6,7], and severe pain [8,9,10]. bMIDAS Grade I, Little or no disability (0–5); MIDAS Grade II, Mild disability [6,7,8,9,10]; MIDAS Grade III, Moderate disability [11,12,13,14,15,16,17,18,19,20]; and MIDAS Grade IV, Severe disability (21+). cHeadache duration, categorized as ≤ 10 h, less than or equal 10 h; >10 more than 10 h. dHeadache frequency, categorized as ≤ 15 days/month and > 15 d. Subjects in the low adherence of DAQS had DAQS (< 5); high adherence: (≥ 5). DAQS, dietary antioxidant quality score; VAS visual analog scale, MIDAS migraine disability assessment
