CRP and diabetes mellitus: In univariate Cox regression analysis, diabetes mellitus (HR: 0.53, 95% CI: 0.34–0.82, p = 0.005), CCI (HR: 2.25, 95% CI: 1.50–3.36, p < 0.001), platelet count (HR: 1.59, 95% CI: 1.09–2.32, p = 0.01), lymphocyte count (HR: 0.63, 95% CI: 0.43–0.91, p = 0.01), CRP level (HR: 1.67, 95% CI: 1.15–2.42, p = 0.007), and culture positivity (HR: 3.29, 95% CI: 2.20–4.92, p < 0.001) were significantly associated with OS.
