Fig. 3From: Association between anion gap and mortality of aortic aneurysm in intensive care unit after open surgerySubgroup analysis of association between serum anion gap and ICU mortality. Horizontal lines represent 95% confidence intervals. OR in each level and Pinteraction were calculated after adjusting for SOFA. AG was significantly associated with in-ICU mortality in total cohort (P value < 0.05), all groups except sepsis identified group (P value = 0.248). Abbreviation: OR, odds ratio; CI, confidence intervals; SOFA, sequential organ failure assessment; AG, anion gap; ICU, intensive care unitBack to article page
