Figure 2From: Leukocytes and systemic inflammatory response syndrome as prognostic factors in pulmonary embolism patients Receiver operating characteristic curves for the 30-day mortality. The curves are based on logistic regression models for risk prediction, incorporating the following: Model 1, PESI (AUC = 0.72; 95% CI, 0.68–0.75); PESI + WBC count (AUC = 0.76; 95% CI, 0.72–0.79), P = 0.008 versus Model 1. PESI: pulmonary embolism severity index; AUC: area under the receiver operating characteristic curve; CI: confidence interval; WBC: white blood cell.Back to article page
