  • Average and SD of the laboratory parameters collected in the first 7 days of hospitalisation in patients with COVID-19 divided according to the new COVID-CS criteria. ORs and p values were calculated by univariate logistic regression. Normal range of values is shown for our laboratory as reference.

  • Abs, absolute numbers; ALT, alanine aminotransferase; AST, aspartate aminotransferase; BUN, blood urea nitrogen; COVID-CS, COVID-19 cytokine storm; LDH, lactate dehydrogenase; WBC, white blood cell.
