The value of interleukin-6 in predicting acute appendicitis in children and distinguishing complicated appendicitis: a systematic review and meta-analysis.
Synthesis in Frontiers in immunology, 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
Objectives: The identification of new, easily measurable biomarkers may assist clinicians in diagnosing and managing acute appendicitis. Although inflammatory markers have been applied in pediatric appendicitis diagnosis, the diagnostic and disease assessment value of interleukin-6 (IL-6) as a key inflammatory factor in this condition has not yet been systematically evaluated. Methods: We conducted a systematic search of electronic databases to identify all studies reporting IL-6 in children with a clinical diagnosis of acute appendicitis. We considered two comparisons: 1) appendicitis versus no appendicitis and 2) uncomplicated appendicitis (UA) versus complicated appendicitis (CA). We converted and analyzed the odds ratios from the multivariate analysis to determine the independent predictive value of IL-6 in pediatric acute appendicitis. Results: Seventeen studies were included in this meta-analysis. These studies enrolled a total of 3,104 patients. The IL-6 levels were significantly higher in patients with acute appendicitis (MD -19.99; 95% CI: -31.19 to -8.79; p = 0.0008; I Conclusion: IL-6 may serve as one of the markers for distinguishing UA from CA, although no clear association was found regarding its independent predictive value. Future prospective studies with larger sample sizes are warranted to establish higher-level evidence.
