Odds ratio for each clinical and laboratory feature against oxygen demand or mortality. The95% confidence interval for odds ratio (OR) for each clinical and laboratory parameter is shown. The following parameters were identified as significant (p < 0.05) for severe COVID-19 (blue dot) by univariate logistic regression analysis: advanced age, fever at presentation, number of comorbidities, pre-existing cardiovascular disease, decreased albumin level, increased levels of aspartate aminotransferase (AST), lactatedehydrogenase (LDH), and lung CT score, increased red cell distribution width (RDW), thrombocytopenia, increased plateletcrit, platelet distribution width (PDW), hypocalcemia and increased BNP and acute phase reactants(inflammatory markers) such as CRP, presepsin, and procalcitonin. Those significant for mortality (red dot) include advanced age, number of comorbidities, pre-existing cardiovascular disease, hypoalbuminemia, increased AST, LDH, RDW, and BNP. Meanwhile, number of vaccination was protective both for severe COVID-19 and mortality. Severe obesity (body mass index > 30 kg/m2). Leukocyte glucose index is defined as the product between blood leukocyte counts and glucose levels divided by 1,000. CT score, lung computed tomography score
