Prognostic Risk Factors of 30-Day Death in Traumatic Lower Limb Fracture Patients with Acute Pulmonary Embolism: A Single-Center Retrospective Study

Figure 6

Incremental model performance for predicting prognosis assessed by starting with the clinical variables (model I PESI score ≥1), followed by Wells score ≥7 (model II: adding Wells score ≥7 to model I), then followed by pulmonary hypertension (model III: adding pulmonary hypertension to model II), and finally by adding anticoagulant therapy (model IV).
