Comparative Evaluation of the Prognostic Accuracy of IL-6 and Angiopoietin-2 for Early Severity Assessment in Acute Pancreatitis: A Systematic Review.
Review in Diseases (Basel, Switzerland), 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
backgroundEarly identification of patients at risk for severe acute pancreatitis (SAP) remains a major clinical challenge. Circulating biomarkers reflecting systemic inflammation (IL-6) and endothelial dysfunction (Ang-2) have emerged as promising tools for improving early prediction of persistent organ failure and other adverse outcomes.
objectiveTo systematically synthesize and compare the diagnostic and prognostic performance of IL-6 and Ang-2 as early biomarkers of severity in adult patients with acute pancreatitis.
methodsThis systematic review was conducted in accordance with PRISMA 2020 guidelines and prospectively registered in PROSPERO (CRD420251177279). PubMed, Scopus, and Web of Science were searched for studies published between 2000 and August 2025. Studies included adult patients (≥18 years) in whom IL-6 and/or Ang-2 levels were measured within 72 h of symptom onset or hospital admission, and where indices of diagnostic accuracy (AUC, sensitivity, specificity, or threshold values) were reported.
resultsFifteen cohort studies met the inclusion criteria. IL-6 demonstrated a consistent association with SAP and persistent organ failure, with AUC values ranging from 0.69 to 0.99; the highest accuracy was observed within the first 24 h. Specificity varied substantially across studies. Ang-2 showed uniformly high prognostic accuracy (AUC 0.79-0.98), reliably predicting persistent organ failure, multiorgan dysfunction, infected necrosis, and mortality.
conclusionsIL-6 exhibits high but heterogeneous diagnostic performance (AUC 0.69-0.99), whereas Ang-2 demonstrates consistently high accuracy (AUC 0.79-0.98) across study designs. Combined evaluation of inflammatory and endothelial pathways appears to offer the most robust strategy for early prediction of persistent organ failure in acute pancreatitis.
