Subsequently, we established the ROC curves to determine which of the biomarkers had a better discriminating power from mild CAP (PSI 1-3) to severe ones (PSI 4-5).RESULTSPCT and proADM significantly discriminated severe from mild CAP, although the area under curve was significantly higher for proADM (0.757 vs. 0.581). The other two biomarkers did not reach statistical significance.CONCLUSIONSProADM is a good predictor of CAP severity at the time of admission, and can be useful, with the clinical scores to identify severe CAP. This may help us to make decisions of patients site of care and management in the early hours.
