- Change From Baseline in Monthly Average Number of Migraine Days During the 4-Week Period at Month 12 [ Time Frame: Baseline (Day -28 to Day -1), Month 12 ]A migraine day was defined as when at least 1 of the following situations occurred: A calendar day(0:00 to 23:59) demonstrating at least 4 consecutive hours (for CM participants) or at least 2 consecutive hours (for EM participants) of a headache meeting criteria for migraine with or without aura; a calendar day(0:00 to 23:59) demonstrating at least 4 consecutive hours (for CM participants) or at least 2 consecutive hours (for EM participants) of a headache meeting criteria for probable migraine, a migraine subtype where only 1 migraine criterion was missing; a calendar day(0:00 to 23:59) demonstrating a headache of any duration that was treated with migraine-specific medications (triptans and ergot compounds). Monthly averages were derived and normalized to 28 days equivalent by formula: (number of days of efficacy variable over relevant period/number of days with assessments recorded in e-diary over relevant period)*28. Change was calculated as post-baseline value - baseline value.
- Change From Baseline in Monthly Average Number of Headache Days of Any Severity During the 4-Week Period at Month 12 [ Time Frame: Baseline (Day -28 to Day -1), Month 12 ]Headaches were subjectively rated by participants as mild, moderate or severe.

Monthly averages were derived and normalized to 28 days equivalent by the following formula: (number of days of efficacy variable over relevant period/number of days with assessments recorded in the e-diary over the relevant period) * 28. The change was calculated as post-baseline value - baseline value.

Monthly averages were derived and normalized to 28 days equivalent by formula: (number of days of efficacy variable over relevant period/number of days with assessments recorded in e-diary over relevant period) * 28.
- Percentage of Participants With At Least 50% Reduction From Baseline in Monthly Average Number of Headache Days of at Least Moderate Severity During the 4-Week Period [ Time Frame: Baseline (Day -28 to Day -1), Month 12 ]Headaches were subjectively rated by participants as mild, moderate or severe. A headache day of at least moderate severity for both CM and EM participants was defined as a calendar day (00:00 to 23:59) where the participant (using the electronic headache diary device) reports: a day with headache pain that lasts at least 4 hours with a peak severity of at least moderate severity or; a day when the participant used acute migraine-specific medication (triptans or ergots) to treat a headache of any severity or duration. Monthly averages were derived and normalized to 28 days equivalent by the following formula: (number of days of efficacy variable over relevant period/number of days with assessments recorded in the e-diary over the relevant period) * 28.
