the analysis, were the significant ones by the preceding univariate
analysis. Results are described by the odds ratio (OR) and 95% confidence
interval (CI). Furthermore, Cox regression models were fitted
for all variables to examine their relationship with time to
sepsis development. The revealed significant variables were then
entered in a multiple Cox regression analysis. Results are described
by the relative risk (RR) and 95% confidence interval (CI). A receiver
operating characteristic (ROC) curve was plotted using sepsis
development during ICU stay as the classification variable and
sE-selectin, sP-selectin, PCT and CRP levels at ICU admission as
prognostic variables. All p-values are two-sided; p < 0.05 were considered
significant.
