Table 5 Recurrence rates according treatment group.

From: Rizatriptan versus rizatriptan plus rofecoxib versus rizatriptan plus tolfenamic acid in the acute treatment of migraine

Treatment Recurrence Rate n/N (%)
RI 11/22 (50%)
RI + RO 6/39 (15.4%)
RI + TA 2/26 (7.7%)
P value P < 0.01 for RI vs RI + RO
P < 0.01 for RI vs RI + TA
P = NS for RI + RO vs RI + TA
  1. RI: rizatriptan; RO: rofecoxib; TA: tolfenamic acid; n: attacks where recurrence were observed; N: number of treated attacks.
