In the multivariate analysis, PUC+ (OR = 2.331; 95% CI: 1.022-5.317), PCT (OR = 1.093; 95% CI: 1.005-1.187), CRP (OR = 1.017; 95% CI: 1.009-1.024), and NEUT% (OR = 1.091; 95% CI: 1.029-1.157) were independently associated with SIRS. This evidence concerns the gene CALCA and systemic inflammatory response syndrome.
