Fig. 2.  Confirmation analysis by NanoString nCounter (Seattle, WA) assay in trauma patients who developed ventilator-associated pneumonia (VAP) and trauma patients who did not develop VAP (controls). Patients were sampled at admission (S1). A second sample (S2) was collected in patients who developed VAP (at the onset of VAP). A second sample was collected in controls between days 5 and 10 (S2). Counts in log2 scale for the five confirmed genes of the concise signature (A ) and five proinflammatory markers (B ) are presented as box plots (green = S1; red = S2 in patients with VAP; blue = S2 in controls).
