Receiver-operator characteristic curves for Random Forest models of the diagnostic performance of biomarkers derived and validated in Cohorts 1 and 2. A). Performance of 16 biomarkers derived from Cohort 1 and validated on Cohort 2 (red curve; AUC 0.84); performance of commonly available biomarkers (ANC, ESR, concentration of A1AT, CRP, and fibrinogen, and platelet count) validated on Cohort 2 (green curve; AUC 0.91); performance of extended set of clinically available biomarkers (commonly available biomarkers from green curve plus ALT and GGT) validated on Cohort 2 (blue curve; AUC 0.92) B). Performance of 11 biomarkers derived from Cohort 2 and validated on Cohort 1(red curve; AUC 0.93); performance of commonly available biomarkers validated on Cohort 1 (green curve; AUC 0.94); performance of extended set of clinically available biomarkers (commonly available biomarkers from green curve plus ALT and GGT) validated on Cohort 1 (blue curve; AUC 0.96).
