Albumin-corrected anion gap predicts acute kidney injury in critically ill patients with acute pancreatitis: a retrospective cohort study.
Article in BMC nephrology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAcute kidney injury (AKI) is a common and serious complication of acute pancreatitis. Early detection of patients at high risk for AKI is critical to avoiding complications and lowering mortality. This study looked into the relationship between albumin-corrected anion gap (ACAG) and AKI in critically ill patients with AP.
methodsAll eligible patients from the Medical Information Marketplace for Critical Care IV database were considered for this study. Kaplan-Meier curves estimated the cumulative risk of AKI and in-hospital mortality. Restricted cubic splines (RCS) and multivariate Cox regression models explored the relationship between ACAG and AKI. Subgroup analyses evaluated the result robustness.
resultsA total of 714 patients were included (mean ACAG: 20.15 ± 5.64; in-hospital mortality: 13.87%; AKI incidence: 70.87%). Kaplan-Meier analysis revealed that the ACAG ≥ 20.25 group exhibited significantly higher AKI incidence and renal replacement therapy(RRT) requirement risk (P < 0.001). Multivariable Cox regression demonstrated ACAG independently associated with AKI risk in AP patients-both as a continuous (HR: 1.12 [95% CI: 1.04-1.21], P = 0.004) and categorical variable (HR: 1.89 [95% CI: 1.11-3.23], P = 0.020). Restricted cubic spline modeling confirmed a linear association between ACAG and increasing AKI risk.
conclusionElevated ACAG levels (≥ 20.25 mmol/L) at ICU admission is associated with a high risk of AKI in critically ill patients with AP.
