Evolution of Revised Amyotrophic Lateral Sclerosis Functional Rating Scale scores over time in subjects successful and unsuccessful with mouthpiece ventilation (MPV). The center lines represent the median value, boxes span the first quartile to the third quartile, and whiskers denote minimum and maximum values that are within 1.5× the interquartile range. Circles are outliers. ALSFRS-R = Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (0–48), b-ALSFRS-R = ALSFRS-R bulbar sub-score (0–12), NIV = noninvasive ventilation.
