Fig. 3From: Central venous pressure and acute kidney injury in critically ill patients with multiple comorbidities: a large retrospective cohort studyOdds ratios for AKI within 7 days associated with CVP in critically ill patients. For categorical variables, all odds ratios (95% CI) and P values were calculated compared with the lowest quartile. For continuous variables, odds ratios (95% CI) corresponded to a 1 mmHg increase in CVP. CVP, central venous pressure; AKI, acute kidney injury; CI, confidence intervalBack to article page
