Univariate regression analysis revealed significant differences between the survival and fatal groups in age, red blood cell count, hemoglobin, platelets, calcium, blood glucose, estimated glomerular filtration rate, alanine transaminase, aspartate aminotransferase, prothrombin time—international normalized ratio, D-dimer, amylase, human placental lactogen, SFTSV-specific IgM antibodies, SFTSV RNA, pancreatitis, gastrointestinal bleeding, mucosal ecchymosis, neurologic symptoms, and urinary protein (all P < 0.05) (Table 1). The gene discussed is F2; the disease is pancreatitis.
