Fig. 4From: Evaluation of novel coronavirus disease (COVID-19) using quantitative lung CT and clinical data: prediction of short-term outcomeA priori analysis for variable selection. The red line is set at area under the curve (AUC) value below 0.5, below which variables predict the response randomly. The blue line is set at AUC value of 0.65. Variables to the right of this line are above a threshold high enough to ensure strong predictive power. WBC, White blood cell countBack to article page
