Figure 2: Time to first protocol-defined relapse during the double-blind period in the overall patient cohort (A), the subgroup seropositive for aquaporin-4 antibodies (B), and the subgroup seronegative for aquaporin-4 antibodies (C).
Patients who did not experience a protocol-defined relapse were censored at the end date of the double-blind period. The dashed lines represent 48 weeks, 96 weeks, and 144 weeks from baseline. The numbers within the figures represent the proportion of relapse-free patients. HR=hazard ratio. NE=not evaluable.
