  • The number of patients is noted in the parentheses. CRP indicates C-reactive protein; LDH, lactate dehydrogenase; AST, asparate aminotransferase; ALT, alanine aminotransferase. For conversion to SI units: leukocyte count, 1/μL = 1 × 106/L; hemoglobin, 1 g/dL = 0.155 mmol/L; platelet count, 1/μL = 1 × 106/L; CRP, 1 mg/dL = 1 × 104 μg/L; blood urea nitrogen, 1 mg/dL = 0.375 mmol urea/L; creatinine, 1 mg/dL = 88.4 μmol/L; LDH, AST, and ALT, 1U/L = 1U/L.
