Defined as the presence of a hypoxic period (SpO2<95%) for >10% of the total sleep time.
Abbreviation: ALSFRSr = Amyotrophic Lateral Sclerosis Functional Rating Scale Revised, ETCO2 = end-tidal carbon dioxide, FVC = forced vital capacity, SpO2 = arterial oxygen saturation measured using pulse oximetry, cluster of desaturation ≥5 desaturations (a decrease in SpO2≥4%) within a 10-min period.
All continuous values are expressed as mean ± standard deviation.
