FIGURE 4.

Proportion of patients achieving ≥50% to ≥90% reduction in attack rate during days 0‐69 relative to the run‐in period. Responders were defined as patients who achieved ≥50% reduction in number of attacks relative to the run‐in period. For each patient, the percentage reduction was calculated as the run‐in period attack rate minus the treatment period attack rate divided by the run‐in period attack rate, multiplied by 100. The percentage reduction groups are not mutually exclusive; patients may appear in more than one group, as applicable, based on their percentage reduction
