Specific elevation of DcR3 serum level in sepsis. The concentrations of DcR3, TL1A and OPG were quantified in sera of patients with sepsis or SIRS. Box and whiskers plots were presented to show median and interquartile (25th–75th) ranges. Protein concentrations were shown in logarithmic scale. P values (ANOVA test) for comparison among Normal, sepsis and SIRS were <0.0001, 0.0017, and 0.5755 for DcR3, OPG and TL1A, respectively. P values (Mann-Whitney test) between sepsis and SIRS were <0.0001, 0.5096, 0.5214 for DcR3, OPG and TL1A, respectively.
