Data expressed as median and IQR [Interquartile Range] (continuous variables) and as column percentages (categorical variables). Percentages may not total 100 because of rounding, Hemocromocytometric values data shown as Hemoglobin, White blood cells and Platelets count. INR = International Normalization Ratio for prothrombin time; aPTT = Activated Partial Thromboplastin Time; AST = Aspartate Aminotransferase; ALT = Alanine Aminotransferase; LDH = Lactate Dehydrogenase; D-dimer = Fibrin Degradation product; CRP = C-reactive Protein; PCT = Procalcitonin; Na = Sodium; K = Potassium; Cl = Chloride. p values obtained by Chi-square test (or Fisher's exact test when appropriate) for categorical variables and Wilcoxon-Mann- Whitney test for continuous variables
