Effects of omega-3 supplementation on gastrointestinal cancers and treatment-related complications: an umbrella review of meta-analyses.
Article in Gastroenterology report, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Background: Many meta-analyses and systematic reviews have explored the impact of omega-3 supplementation on clinical outcomes in individuals with gastrointestinal (GI) cancers. Thus, this study aimed to capture the effects of omega-3 supplementation on GI cancers and associated complications. Methods: This umbrella study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive advanced search was executed across Scopus, PubMed, and Web of Science until 25 January 2025. Data were pooled by using random-effects models based on heterogeneity. The entire statistical analysis was performed via RStudio and R. The statistical analysis results are presented as the mean difference (MD), standard mean difference (SMD), and relative risk (RR) in conjunction with their 95% confidence intervals (CIs). Results: Eight meta-analysis papers were included in our umbrella review. Omega-3 fatty acid supplementation improved the serum concentrations of tumor necrosis factor alpha (TNF-α) (SMD: -0.34; 95% CI: -0.56, -0.11), interleukin-6 (IL-6) (SMD: -0.30; 95% CI: -0.49, -0.12; MD: -4.96; 95% CI: -6.62, -3.30), and C-reactive protein (CRP) (MD: -5.46; 95% CI: -10.06, -0.87). Omega-3 supplementation improved the CD4 Conclusion: Omega-3 supplementation may reduce the risk of overall complications and length of hospitalization in individuals suffering from GI cancers. Additionally, supplementation with omega-3 may alleviate the levels of pro-inflammatory cytokines such as TNF-α and IL-6, and acute-phase proteins such as CRP.
