IL6 and Sepsis: The TNF-α level was positively correlated with WBC, SAA, and IL-6 in the sepsis group (r = 0.320, p = 0.007; r = 0.379, p = 0.001; and r = 0.401, p = 0.001, respectively), but there was no correlation between the level of TNF-α and CRP, APACHE II, and the SOFA score (r = 0.103, p = 0.395; r = 0.152, p = 0.209; and r = 0.009, p = 0.942, respectively), as shown in Figure 3.
