3. Fig. 2
Receiver operating characteristics (ROC) curves of C-reactive protein (CRP) (solid line), temperature (dashed line) and white cell count (WCC) (dotted line) in the diagnosis of infection. The area under the curve for CRP was significantly higher than that for temperature and WCC (p < 0.001).

Influence of the origin (i.e., infectious or non-infectious) and severity of the critical illness on CRP levels. Infected and non-infected patients were divided into four clinical groups according to the ACCP/SCCM Consensus Conference criteria [12], namely absence of the systemic inflammatory response syndrome (no-SIRS), SIRS, severe sepsis, and shock. In each degree of clinical severity, infected patients had a significantly higher CRP level than non-infected patients (*p < 0.001).
