The predictive factor neutrophil-to-lymphocyte ratio (NLR) was selected using LASSO regression analysis. a LASSO coefficient profiles of the non-zero variables of COVID-19 pneumonia. b Partial likelihood deviance plot of the lowest point of the red curve (solid line), which corresponds to a three-variable model. The dashed line on the right is a more concise model within one standard error (the number of variables is one)
