Mean CNS-LS Scores Across DM/Q Studies for PBA Secondary to Diverse Neurologic Conditions. *DM/Q 30/30 mg twice daily; †DM/Q 20/10 mg twice daily. ‡Improvement from baseline in mean CNS-LS (SE). 99-AVR-102 (4 week study comparing DM/Q to DM or Q monotherapy): End of study is the mean of the CNS-LS scores for Days 15 and 29; P = 0.001 vs. dextromethorphan comparator and P < 0.001 vs quinidine comparator. 02-AVR-106 (12 week DBPC study): End of study is the mean of the CNS-LS scores on Days 15, 29, 57, and 85; P < 0.0001 vs. placebo. 07-AVR-123 (12 week DBPC study): End of study is at Week 12 intent to treat; P < 0.05 vs. placebo. PRISM II: End of study is at Day 90/Final Visit; P < 0.001 vs. baseline in all 3 cohorts. ALS = amyotrophic lateral sclerosis; CNS-LS = Center for Neurologic Study–Lability Scale; DM/Q = dextromethorphan/quinidine; MS = multiple sclerosis; PBA = pseudobulbar affect; TBI = traumatic brain injury; SE = standard error
The following statement should not have been included in the caption of Fig. 3: “CNS-LS scores were not normalized.” The CNS-LS is a rank-order scale, and is not normalized. This statement was included erroneously and the authors intended on removing it prior to resubmission, but this was unfortunately overlooked.
Similarly, the y-axis within Fig. 6 was mislabelled. The CNS-LS scale ranges from 7 to 35, so the y-axis for Fig. 6 should start at a base score of 7 and not zero. The correct and updated version of Fig. 6, in which the data presented remain accurate and are unchanged, is published in this erratum.
