In the analysis of ≥ 30% reduction in FPI at week 9, the efficacy of propranolol was greater among migraineurs (adjusted odds ratio [AOR] = 3.3; 95% CL = 1.4, 8.1; p = 0.009; NNT = 3.7) than non-migraineurs (AOR = 1.3; 95% CL = 0.5, 3.2; p = 0.631; NNT = 18.7) although the test for migraine by treatment group interaction did not reach statistical significance ( p = 0.139) ( Table 2 ).
