Association between adherence to the Mediterranean Diet and pancreatic cancer risk: a systematic review and meta-analysis.
Synthesis in Frontiers in nutrition, 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: Pancreatic cancer (PC) is one of the most lethal malignancies with a poor prognosis. Although the Mediterranean Diet (MedDiet) is hypothesized to be inversely associated with PC risk, epidemiological findings remain inconsistent. This meta-analysis aims to quantitatively evaluate the association between Mediterranean Diet adherence and the risk of developing pancreatic cancer by synthesizing the most recent evidence. Methods: A systematic search was performed across PubMed, Web of Science, Embase, and the Cochrane Library for observational studies investigating MedDiet and PC risk. Data were synthesized using both continuous and categorical variable analyses. Given the anticipated heterogeneity, a random-effects model was applied to pool the effect estimates. Results: Fourteen studies (12 cohorts and 2 case-control studies) were eligible for inclusion. In the continuous analysis, a higher MedDiet adherence score was associated with a lower risk of PC (pooled relative effect estimates per one-unit increase within the respective scoring system = 0.96, 95% CI: 0.94-0.97; I Conclusion: This meta-analysis suggests an inverse association between higher adherence to the MedDiet and pancreatic cancer risk. However, the observational nature of the available evidence limits causal inference. Further well-designed prospective studies and dietary intervention trials are warranted to confirm this association and clarify its potential implications for pancreatic cancer prevention.
