Figure 1: Estimated Probability Of Achieving An Initial Headache Response By 2 Hours In Pooled Studies 1, 2, 3, And 4†† (Rizatriptan Fig1)
Figure 1 shows the Kaplan-Meier plot of the probability over time of obtaining headache response (no or mild pain) following treatment with rizatriptan benzoate or placebo. The averages displayed are based on pooled data from 4 placebo-controlled, outpatient trials providing evidence of efficacy (Studies 1, 2, 3, and 4). Patients taking additional treatment or not achieving headache response prior to 2 hours were censored at 2 hours. The chart displays the estimated probability of response based on the hours post-dose and the percentage rates for achieving an initial headache response. The data is presented for Placebo, Rizatriptan Benzoate 5 mg, and Rizatriptan Benzoate 10 mg.*
