Pilot study of a novel serum mRNA gene panel for diagnosis of acute septic arthritis

Figure 1 ROC curves for separating infectious from non-infectious joint infections. A: Sepsis Metascore area under the ROC = 0.87; B: Erythrocyte sedimentation rate area under the ROC = 0.58; C: C-reactive protein area under the ROC = 0.6; D: White blood cell area under the ROC = 0.59; E. Synovial cell area under the ROC = 0.54; F: Synovial polymorphonuclear cells % area under the ROC = 0.51. WBC: White blood cell; ESR: Erythrocyte sedimentation rate; CRP: C-reactive protein; SMS: Sepsis MetaScore.
