a F-values and p-values were calculated with univariate linear regression.
b Feng et al. (2020) reported these features as risk factors of pneumonia progression and correlated to CT severity score. Abbreviations WBC - White Blood Cell count; NLR - Neutrophil-to-Lymphocyte Ratio; ALT - Alanine aminotransferase; AST - Aspartate aminotransferase; CK - Creatinine Kinase; LDH - Lactic dehydrogenase; CRP - C-Reactive Protein.
