Fig. 2

ROC curves showing the area under the curve (AUC) and cut-off points for the different variables associated with the non-survival condition in the bivariate analysis. A PaFiO2 at 24, 48 and 72 h; B Ferritin at 24 h, IL-6 at 24 h, and LDH at 24 h; C NLR 24, 48 and 72 h; D SOFA at 24, 48 and 72 h. PaFiO2: ratio of arterial oxygen partial pressure (PaO2 in mmHg) to fractional inspired oxygen; LDH: lactate dehydrogenase; IL: interleukin; NLR: neutrophil-to-lymphocyte ratio; SOFA: Sequential Organ Failure Assessment Score
