Mean (SD) CNS-LS Score at Baseline, Day 30, and Day 90 (Effectiveness Analysis Set). CNS-LS scores range from 7 to 35, with higher scores indicating increased frequency and severity of PBA episodes. P values are based on the one sample t-test and represent comparison with baseline. *P < .001 vs. baseline. †The CNS-LS is a patient-reported quantitative measure of the perceived frequency and severity of PBA episodes; CNS-LS scores were not normalized. CNS-LS = Center for Neurologic Study–Lability Scale; PBA = pseudobulbar affect; SD = standard deviation
