Data from the index admission only.
* In 11 patients we did not have spirometry.
† In two of the patients we did not have data on smoking habits.
BMI, body mass index; CRP, C-reactive protein; FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; MAP, mean arterial pressure; Paco2, partial arterial CO2 pressure; Pao2, partial arterial O2 pressure; Sao2, arterial O2 saturation.
