Changes in AUROC for each combination of the order of biomarkers in the XGBoost model. Figures show the relationship between each biomarker and the AUROC for the primary outcome using the XGBoost model: panel (A) indicates the change in the AUROC of CRP when the cut-off values of the other two biomarkers were fixed. Similarly, panels (B,C) indicate changes in the AUROCs of albumin and lymphocyte count when the cut-off values of the other two biomarkers were fixed. Each panel contains the results of six combinations of the order of biomarkers. Abbreviations: AUROC, area under the receiver operating characteristic; CRP, C reactive protein.
