We collected the maximum serum AG value within the first 24 hours of ICU admission. The main outcome was 90-day all-cause mortality. A multivariate Cox proportional hazard regression model was used to examine the association between the serum AG and mortality. The restricted cubic spline curve was used to confirm a non-linear relationship between serum AG values and mortality.Results: Of the 279 patients included in the study, 87 (31.18%) died. The serum AG value was positively associated with 90-day all-cause mortality (hazard ratio [HR] 1.08, 95% confidence interval [CI] 1.02– 1.14), after adjusting for age, sex, alcohol consumption, congestive heart failure, diabetes mellitus, hypertension, eGFR, albumin, and the SOFA score. There was a non-linear relationship between serum AG values and mortality after adjusting for potential confounders. We used a two-piecewise regression model to obtain a threshold inflection point value of 13.8 mmol/L. The HR and the 95% CI on the left inflection point were 0. 82 (0.61– 1.09; p = 0.1719), and on the right inflection point were 1.15 (1.08– 1.23; p < 0.0001).Conclusion: The relationship between all-cause mortality in patients with acute pancreatitis and serum AG values was non-linear. All-cause mortality and serum AG values were positively correlated when the serum AG value was > 13.8 mmol/L.Keywords: anion gap, all-cause mortality, acute pancreatitis, MIMIC III databasehttps://www.dovepress.com/the-relationship-between-the-serum-anion-gap-and-all-cause-mortality-i-peer-reviewed-article-IJGManion gapall-cause mortalityacute pancreatitismimic iii database |
