Hierarchical binary recursive partitioning algorithm to predict mean PAP ≥ 40 mmHg in COPD patients.
The model correctly classified the 16 COPD patients (100%) with mean PAP ≥ 40 mmHg and 75 out of 126 (59.5%) patients who had a mean PAP < 40 mmHg. The model precision was 24 % with an AUC by ROC of 0.80. Abbreviations: mPAP: mean pulmonary artery pressure.
