Correlation of red cell distribution width-to-albumin ratio combined with SOFA score with 28-day all-cause mortality in patients with acute pancreatitis: A retrospective study based on the MIMIC-IV database.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThe objective of this study is to evaluate the effectiveness of the red cell distribution width-to-albumin ratio (RAR) in conjunction with the Sequential Organ Failure Assessment (SOFA) score for predicting 28-day all-cause mortality in patients with acute pancreatitis (AP).
methodsIn this study, we conducted a retrospective analysis of clinical data from 702 patients with AP sourced from the MIMIC-IV (v3.1) database. We evaluated the relationship between the RAR-modified SOFA score and 28-day all-cause mortality using both univariate and multivariate Cox regression analyses. Furthermore, the optimal cutoff value was determined using the Youden index, and the predictive performance of the combined indicator was evaluated through Receiver Operating Characteristic (ROC) curves and Kaplan-Meier (K-M) survival analysis. Finally, we examined the robustness of our findings across different populations through subgroup analyses.
resultsA total of 702 patients with AP admitted to the Intensive Care Unit (ICU) were included in this study, and their 28-day all-cause mortality was analyzed. Both univariate and multivariate Cox regression analyses indicated that the RAR-modified SOFA score served as an independent risk factor for 28-day all-cause mortality in ICU patients with AP. ROC curve analysis demonstrated that the RAR-modified SOFA score exhibited superior predictive ability compared to other scoring systems, including RAR and SOFA alone. Additionally, K-M survival curve analysis revealed that the mortality rate was significantly higher in the high-value group (RAR-modified SOFA score ≥ 12.69) compared to the low-value group (RAR-modified SOFA score < 12.69).
conclusionsThe RAR-modified SOFA score significantly enhances the predictive accuracy for 28-day all-cause mortality in patients with AP.
