IL6 and Sepsis: Multivariate logistic regression analysis demonstrated that APACHE II score (odds ratio [OR] = 1.166, 95% confidence interval [95% confidence interval [CI]] 1.005–1.352, P = .042), IL-6 (OR = 1.001, 95% CI 1.000–1.001, P = .003) and NSE (day4) (OR = 1.099, 95% CI 1.027–1.176, P = .006) were independently associated with the ICU mortality of sepsis shock patients.
