CRP and Sepsis: In the patient group <65 years, univariate logistic regression analysis revealed significant associations between sepsis and blunt trauma (OR = 1.69, p = 0.013), ISS (OR = 1.02, p < 0.001), ATLS shock class (OR = 1.15, p = 0.016), leucocytes (OR = 1.02, p = 0.027), CRP (OR = 1.00, p = 0.010), hemoglobin (OR = 0.96, p = 0.027) and hematocrit at admission (OR = 0.98, p = 0.012).
