Fig. 2From: Early warning of bloodstream infection in elderly patients with circulating microparticlesReceiver operating characteristic (ROC) curve to evaluate the predictive value of early warning model and other factors for predicting bloodstream infection in the elderly population. Area under the curve of warning model was 0.884 (95%CI 0.826–0.942, P < 0.0001). PCT: procalcitonin; T-MPs: total microparticles; LMPs: leukocyte-derived microparticles; NMPs: neutrophil-derived microparticles; 1: within 6 h; 2: day 2Back to article page
