Independent-samples t-tests were applied to the comparison of the frequency of headache between the clinically significant improvement and no significant improvement groups. Headache frequency responder, frequency of headache in the clinically significant improvement group; non-responder, frequency of headache in the no significant improvement group. *Independent-samples t-tests were significant at the 0.01 level.
