Hierarchical Configuration of Classifiers used for Risk Assessment for Each Endpoint. A Diagnostic Cortex model with in-bag decision tree model (represented by the top box) was used to stratify the entire development cohort into a higher and lower risk group for each endpoint. Diagnostic Cortex models (middle boxes) without trees were used to split the resulting two groups further according to one of the two schemas. (Schema A was used for the tests predicting risk of any complication and intubation. Schema B was used for the tests predicting risk of ARDS and admission to the ICU.)
