Data are presented as mean±sd or %, unless stated otherwise. ALI: acute lung injury; CPE: cardiogenic pulmonary oedema; LIS: lung injury score; SAPS II: simplified acute physiology score II; A–a oxygen difference: highest alveolar–arterial oxygen difference on the day of oedema fluid sampling; EF/PL: oedema fluid-to-plasma protein ratio. ***: p<0.001 versus CPE group; ###: p<0.001 versus CPE group and mixed aetiology group.
