IL6 and Sepsis: When comparing G1 controls with G4 patients (considered as sepsis patients), a panel (Model A) made of kynurenine: tryptophan (OR = 5.59, p = 0.039, SE = 0.69), IL-6 (OR = 6.91, p = 0.019, SE = 0.82), LysoPC a C18:2 (OR = 0.06, p = 0.022, SE = 1.23), and phenylalanine (OR = 7.63, p = 0.019, SE = 0.83) was built.
