Cox proportional hazards analysis for 180-day mortality (CRP/albumin ratio at 72 h after admission).

1The hazard ratio (HR) for death is expressed per 1-y increase in age, female to male in gender, per 1 score increase in the SOFA score, 1 mg/L increase in CRP, 1 g/L decrease in albumin, 1 increase in CRP(mg/dL)/albumin(g/L), 1 mmol/dL increase in lactate and having malignancy to having no malignancy. The multivariate analysis was adjusted for covariates such as age, gender, CRP/albumin ratio, SOFA score, lactate level and having malignancy or not, for each variable. Abbreviation: SOFA, sequential organ failure assessment; CRP, C-reactive protein. Cox proportional hazards analysis for 180-day mortality (CRP/albumin ratio at 72 h after admission).
