CRP and diabetes mellitus: After performing a multivariate stepwise Cox regression model adjusted for age, gender, hypertension, diabetes, COPD, dependency, lymphopaenia, anaemia (haemoglobin < 10 g/dL), serum creatinine, CRP > 60 mg/L, LDH > 400 U/L and D-dimer > 1000 ng/mL, elevated admission BG levels remained a significant predictor of death compared to BG <140 mg/dL, with the following findings: BG >180 mg/dL (HR 1.50, 95%CI: 1.31–1.73; p<.001) and BG 140–180 mg/dL (HR 1.48, 95%CI: 1.29–1.70; p<.001).
