  1. Correlations were calculated by Spearman correlation analysis (r). a, the immunological parameters and tissue damage parameters were analyzed in all enrolled patients (n = 135); b, coagulation parameters were measured in 60 patients according to the needs of clinical examination. Mild, n = 19; Severe, n = 41. Abbreviations: WBC, white blood cells; CRP, C-reactive protein; PT, thrombin time; FDP, fibrin(-ogen) degradation products; PTA, prothrombin activity; INR, international normalized ratio; LDH, lactate dehydrogenase; DBIL, direct bilirubin; TBIL, total bilirubin; CK, creatine kinase; GFR, glomerular filtration rate
  2. P < 0.05 was considered statistically significant and is shown in bold
