Carmona-Bayonas 2017 EPIPHANY CHAID tree for cancer-associated PE

Carmona-Bayonas 2017 EPIPHANY CHAID tree for cancer-associated PE. Hestia-like CDR any vs none, then ECOG-PS, SaO2, PE symptoms, tumour response, and primary resection as in Figure 2. Returns low, intermediate, or high with 15-day complication rates 1.6/9.4/30.6% and mortality 0.3/6.1/17.1%. Caller assigns the six covariates. Not a diagnosis or anticoagulation order. magent does not examine the patient.
