  1. DeLong test was used to compare the AUROC between fibrinogen and other biomarkers and estimate P values and fibrinogen was the reference. AUROC area under the receiver operating characteristic curve; CI confidence interval; PV + positive predictive value; PV − negative predictive value; LR + positive likelihood ratio; LR − negative likelihood ratio; RDW red cell distribution width; ESR erythrocyte sedimentation rate; CRP C-reactive protein; NLR neutrophil to lymphocyte ratio; PLR platelet to lymphocyte ratio; LMR lymphocyte to monocyte ratio
