CRP and diabetes mellitus: Multivariable regression analysis confirmed diabetes mellitus (p < 0.001, HR 7.096, CI 0.95% 3.098–16.253) as the strongest predictor for lethal outcome followed by CRP (p < 0.022, HR 1.009, CI 0, 95% 1.001–1.016) and ferritin level (p < 0.013, HR 1.001, CI 0.95% 1.000–1.002; Table 4).
