Table 1.
Patients’ demographic and laboratory findings at admission. M: male, F: female. Laboratory tests are expressed as median values and Interquartile range (IQR): LDH: lactate Dehydrogenase, AST: aspartate aminotransferase, ALT: alanine aminotransferase, CK: creatine kinase, CRP: c-reactive protein. PaO2/FiO2: partial pressure of arterial oxygen (PaO2) to fraction of inspired oxygen (FiO2) ratio (number and percentage of patients for the different subclasses of ARDS).
