ALB and diabetes mellitus: Multivariate logistic analysis showed that increased APACHE II score [odds ratio (OR) = 1.146; 95% confidence interval (CI), 1.059–1.240], decreased ALB level (OR = 0.867; 95%CI, 0.758–0.990), diabetes (OR = 9.591; 95%CI, 1.766–52.075) and high PCT level (OR = 1.051; 95%CI, 1.005–1.099) were independent risk factors for septic shock (Fig. 2).
