ICU, intensive care unit; ISS, injury severity score; SOFA, Sepsis-related Organ Failure Assessment; Hgb, hemoglobin; INR, international normalized ratio; PC, platelet concentrate; NE, norepinephrine; CT fib, clotting time FIBTEM (ROTEM); CVVHDF, continuous veno-venous hemodiafiltration; ASA, American Society of Anesthesiology score. Rho represents the Spearman correlation coefficient. A two-sided P-value <0.05 was considered statistically significant; significant P-values are indicated in bold print.
