End point description |
Pain relief was defined as at least a 2-grade reduction in pain intensity on a 5-grade scale in participants who had not used headache rescue medication before assessment. A pain intensity score of 5 was assigned for all subsequent assessments if a participant took rescue medication (a single oral dose for the treatment of migraine pain or associated symptoms). The 5-grade scale is a participant's self-rating scale to assess the pain intensity of a migraine with the following scores: 1 = none, 2 = mild, 3 = mild to moderate, 4 = moderate to severe, and 5 = severe.
