Figure 1: Estimated Probability Of Achieving An Initial Headache Response By 2 Hours In Pooled Studies 1, 2, 3, And 4†† (Rizatriptan Fig1)
The image depicts a graph showing the estimated probability of achieving a headache response within 2 hours of treatment with rizatriptan benzoate or placebo. The data presented in the graph is obtained by pooling data from four outpatient trials showing evidence of efficacy. The graph shows the Kaplan-Meier plot of the probability over time. Patients who did not achieve a headache response within 2 hours or were taking additional treatment were censored at 2 hours.*
