In terms of the values after the onset of VAP, CRP was still able to discriminate between VAP and nonVAP patients, especially on day 1 and day 2, when the median values were even higher than those on day 0 (14.3 mg/dL and 15.85 mg/dL vs. 12.60 mg/dL, respectively). The gene discussed is CRP; the disease is ventilator-associated pneumonia.
