  1. Quantitative variables were summarized using medians, [IQ25–75] and (min – max), while categories were described by numbers and (%). The total percentage for interfaces is > 100% because multiple interfaces were used by 2 patients
  2. Significant pairwise comparisons with Holm corrections are presented a for CSA vs. OSA groups
  3. CSA Central sleep apnea, EPAP Expiratory positive airway pressure, IPS Inspiratory pressure support, max maximum, min minimum, OSA Obstructive sleep apnea, Pmax maximum pressure, RR Respiratory rate, TECSA Treatment emergent central sleep apnea, Ti min Inspiratory support minimum pressurization time
  4. bFor ASV-setting variables shared by both manufacturers, the data were pooled (EPAP (fixed or minimum/maximum); IPS (minimum and maximum), Pmax, RR or auto RR)
  5. cFor slope level and minimum inspiratory time, the data concern only Philips Respironics devices
