- Results of the diagnostic tests for the clinical parameters temperature, C-reactive protein (CRP), the Systemic Inflammatory Response Syndrome (SIRS) and the Combination test (Temperature >38°C, or a CRP > 100 mg/dL or ≥2 SIRS criteria). Analysed in all adult Medical Emergency Department patients (n = 11,988). PPV: Positive Predictive Value. NPV: Negative Predictive Value. +LR: Positive Likelihood Ratio, −LR: Negative Likelihood Ratio. CI: 95% Confidence Interval.
- *: Non blood-cultured and blood cultured non-bacteraemic patients. The percent is presented horizontally.
