The Prognostic Value of Red Blood Cell Distribution Width-to-Albumin Ratio (RAR) in Predicting Mortality and Severity in Acute Pancreatitis: A Systematic Review and Meta-Analysis.
Review in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Acute pancreatitis is a potentially life-threatening inflammatory condition with variable clinical presentations. Early risk stratification remains challenging despite existing scoring systems. The red blood cell distribution width-to-albumin ratio (RAR) has emerged as a potential prognostic biomarker in inflammatory conditions. This systematic review and meta-analysis aimed to evaluate the association between admission RAR and outcomes in acute pancreatitis. We conducted a comprehensive literature search and identified five retrospective studies meeting the inclusion criteria. Meta-analysis was performed to assess the relationship between RAR and mortality as well as disease severity in acute pancreatitis patients. Pooled analysis demonstrated that elevated RAR was significantly associated with increased mortality risk (risk ratio (RR): 2.11, 95% confidence interval (95% CI): 1.35-3.30) with moderate heterogeneity (I²: 46%). When comparing disease severity, mean RAR values were significantly lower in mild acute pancreatitis compared to severe cases (mean difference (MD): -1.78, 95% CI: -2.09 to -1.46), also with moderate heterogeneity (I²: 44%). This meta-analysis suggests that RAR, a simple and cost-effective biomarker available from routine blood tests, may serve as a valuable prognostic indicator for mortality and severity in acute pancreatitis. Despite having comparatively lower discriminative ability than conventional scoring systems, RAR offers advantages in terms of rapid assessment and cost efficiency. However, limitations include the small number of included studies, their retrospective nature, and heterogeneity in study settings. Further prospective studies are warranted to validate these findings.
