A significant, but weak, correlation between BDNF D0 and DCFD (r = 0.31; P = 0.01), as well a mild correlation between BDNF D2 and DCFD (r = 0.44; P < 0.001) were observed In the linear regression BDNF D2 levels (unstandardized B 6.95 (2.3 to 9.7); P = 0.002), but not BDFN D0 (unstandardized B 2.05 (-2.4 to 6.5); P = 0.36) and sepsis (unstandardized B -3.4 (-6.7 to -0.08); P = 0.045) were independently associated with DCFD. This evidence concerns the gene BDNF and Sepsis.
