Characterization of immune cell subsets at the onset of sepsis. Peripheral blood was collected from patients within 24 hours of the onset of severe sepsis and from controls and analyzed by flow cytometry to determine the percentage of circulating cells of each subset. The markers used to identify each subset are described in the methods. Horizontal lines indicate the mean value. P values were calculated by a non-parametric 2-tailedMann-Whitney U-test.
