Variables were summarized using medians, [IQ₂₅–₇₅] and (min – max)
*Note that for Philips Respironics® devices, the minute-ventilation is expressed as “mean” in the manufacturer software whereas for ResMed® devices, the minute-ventilation is expressed as “median” (thus preventing direct comparisons between these device types)
