Data expressed as an absolute number.

ARB: angiotensin II receptor blocker; COPD: chronic obstructive pulmonary disease; 95% CI: 95% confidence interval; ACEI: angiotensin converting enzyme inhibitor; OR: odds ratio; p: value of statistical significance; PaO₂FiO₂: ratio of partial pressure of oxygen in arterial blood/fraction of inspired oxygen; OSAS: obstructive sleep apnoea syndrome.

Univariate analysis.

Multivariate analysis adjusted to statistically significant variables in the univariate analysis (COPD, CURB65, PaO₂/FiO₂ on admission).
