Headache
-
The objective of this study was to examine if patients with migraine who responded sufficiently to acute treatment were significantly different from those who did not in terms of patient characteristics, treatment patterns, and patient level of impairment, and to identify characteristics associated with insufficient response. ⋯ Clinical characteristics, treatment patterns, and health-related quality of life measures are statistically significantly different between insufficient responders and responders to acute treatment in patients with migraine.
