1.Clinical manifestations:(AKI vs. non-AKI)-Respiratory rate, breaths/min (22.3 vs. 20.6, p<0.001); pulse oximetry (91.7 vs. 94.3%, p<0.001).2. Initial laboratory data:-WBC (9.3 vs. 7.8, p<0.001); Neutrophil (7.3 vs. 5.8, p<0.001); neutrophil-lymphocyte ratio (6.6 vs. 4.7, p<0.001); procalcitonin (0.4 vs. 0.2, p<0.001); fibrinogen (659.1 vs. 631.8, p=0.002); CRP (13.2 vs. 7.3, p<0.001); D-dimer (2.2 vs. 1.1, p<0.001); LDH (458 vs. 350, p<0.001); Ferritin (911 vs. 610, p<0.001). This evidence concerns the gene CRP and acute kidney injury.
