Predicted marginal means (with pointwise 95% confidence intervals) for (a) the incidence of vertigo attacks (primary efficacy outcome) and (b) vertigo days per 30 days during the 6-month treatment period (full analysis set population). A Poisson random intercept and slope model was applied for the principal analysis. The grey shaded area represents the 90-day time period of primary interest comprising of estimated monthly incidences rates for months 4 to 6
