Biomarker-based ARDS Mortality Risk Stratification Model decision tree. The derived biomarker-based ARDS Mortality Risk Stratification Model decision tree from the random 80% derivation cohort (n = 202, 44 non-survivors). The tree contains the mortality probability, macrophage migration inhibitory factor (MIF), interleukin 8 (IL-8), interleukin 6 (IL-6), and extracellular nicotinamide phosphoribosyltransferase (NAMPT). Biomarker concentrations are expressed in ng/ml. Terminal nodes (TN) 1 and TN3 were low risk (15% and 17% risk of death), TN2 and TN4 were intermediate risk (24% and 45% risk of death, respectively), and TN5 high risk (85% risk)
