MBS included nausea, phonophobia or photophobia. MBS were measured using a binary scale as 0= absent, 1= present. Participants who had score of 0 (MBS absent) were considered to have freedom from MBS. Exact 95% CI was based on Clopper-Pearson method.
Pain was measured on a 4-point Likert scale, with following scores: 0= none, 1= mild, 2= moderate, 3= severe. Participants with score of 0 (no pain) were considered to have freedom from pain. Exact 95 percent (%) confidence interval (CI) was based on Clopper-Pearson method.
Participants rated the level of disability they perceived as a result of their migraine in performing normal actions using following level of severity: normal function, mild impairment, severe impairment, or required bedrest. This outcome measure was analyzed only among those participants who reported any impairment at baseline. Percentage of participants with a response of "normal function" at the 2 hours post-dose were reported in this outcome measure.
Pain was measured on a 4-point Likert scale, with following scores: 0= none, 1= mild, 2= moderate, 3= severe. Participants with score of 0 (with no pain) through 2 to 24 hours post-dose were considered to have sustained pain freedom. Exact 95% CI was based on Clopper-Pearson method.
Pain was measured on a 4-point Likert scale, with following scores: 0= none, 1= mild, 2= moderate, 3= severe. Participants with score of 0 (with no pain) through 2 to 48 hours post-dose were considered to have sustained pain freedom. Exact 95% CI was based on Clopper-Pearson method.
Pain was measured on a 4-point Likert scale, with following scores: 0= none, 1= mild, 2= moderate, 3= severe. Percentage of participants who reported a pain level of moderate or severe just before taking study treatment and then reported a pain level of none at the specified timepoints. Exact 95% CI was based on Clopper-Pearson method.
MBS included nausea, phonophobia or photophobia. MBS were measured using a binary scale as 0= absent, 1= present. Participants who had score of 0 (MBS absent) were considered to have freedom from MBS at the specified timepoints. Exact 95% CI was based on Clopper-Pearson method.
Percentage of participants who used rescue medications within 24 hours of administration of study drug were reported in this outcome measure. Exact 95% CI was based on Clopper-Pearson method.
Pain was measured on a 4-point Likert scale, with following scores: 0= none, 1= mild, 2= moderate, 3= severe. This outcome measure was analyzed only in those participants who were pain free at 2 hours post-dose. Percentage of participants who were pain free at 2 hours post-dose and then had a migraine of any pain severity (score 2 or 3 on the 4-point scale) within 48 hours after administration of study drug were considered to have pain relapse. Exact 95% CI was based on Clopper-Pearson method.
Pain was measured on a 4-point Likert scale, with following scores: 0= none, 1= mild, 2= moderate, 3= severe. Participants who reported a pain level of moderate or severe at baseline and then reported a pain level of none or mild at 2 hours post-dose, were considered to have pain relief. Exact 95% CI was based on Clopper-Pearson method.
