Correlation matrix of clinical severity and plasmatic levels of inflammatory biomarkers on intensive care unit admission. Spearman’s correlations are computed amongst all variables. Positive correlations are represented by red squares and negative correlations by blue squares. Darker colors represent higher correlation coefficient. FiO2: inspired oxygen fraction; PaO2: partial arterial pressure of oxygen NT-proBNP: N-terminal pro B-type natriuretic peptide; SOFA: sepsis-related organ failure assessment; SAPS: simplified acute physiology score
