Recursive partitioning using conditional inference trees. Starting from the top, important variables and their respective cutoffs are presented leading (bottom) to the percentage of patients (within each population partition) developing cardiac-surgery-associated acute kidney injury (CSA-AKI). For example, from the group of patients with additive Euroscore <5 and growth-differentiation factor-15 (GDF-15) <1.271 ng/ml, 10 % developed CSA-AKI (Node 3), whereas from the group of patients with additive Euroscore <5 and GDF-15 > 1.271 ng/ml, 20 % of patients developed CSA-AKI (Node 4).
