Table 2

Baseline and outcome characteristics of included patients by pH threshold.

Outcome is defined as a categorical variable and patients can only be included in one category, i.e., domiciliary NIV setup implies completion of acute inpatient NIV episode, and inpatient death implies NIV failure. ^†Of patients who died within two years. SD: standard deviation; BMI: body mass index; PaCO2: arterial partial pressure of carbon dioxide; kPa: kilopascals; mmol/L: millimoles per litre; NIV: noninvasive ventilation; IQR: interquartile range; ITU: intensive treatment unit.
