Factors associated with hospitalization duration in moderate patients and disease progression in severely ill patients. a Moderated patients. b Severely ill patients. CRP, C-reactive protein; LDH, lactate dehydrogenase; NLR, neutrophil-to-lymphocyte ratio. ORs (95% CI) and p-values were calculated using a multivariate logistic regression analysis adjusted the variables with p < 0.05 in the univariate logistic regression analyses. * indicates p < 0.05. β is the regression coefficient of the multivariate logistic regression model. Risk scores were assigned by the weighted point of factors which simplified by the integer form of the quotient of one factor's regression coefficient and the lowest regression coefficient
