ALT = alanine transaminase; APTT = activated thromboplastin time; AST = aspartate transaminase; CRP = C-reactive protein; INR = international normalized ratio; PT = prothrombin time; WBC = white blood cell count. Continuous variables are presented as median (interquartile range).
The P value shows the differences between the two severity groups.
