Mean ± SD	4.5 ± 4.5	13 ± 4.7	11 ± 6.2	144 ± 39

Days of ARDS mean period from ARDS diagnosis until death. PEEP corresponds to mean values in the first 48 h, PaO2/FiO2 ratio of arterial oxygen tension to the fraction of inspired oxygen, PEEP positive end-expiratory pressure. PaO2/FiO2 corresponds to values assessed at the time of clinical diagnosis for each patient
