Methionine Intake, Dietary Acid Load, and Breast Cancer Risk: A Case-control Study.
Article in Journal of cancer prevention, 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
Limited epidemiologic evidence links cancer risk to dietary acid load and methionine intake. Acid stress and metabolic acidosis are closely related to cancer development. Methionine is the main acidogenic amino acid and exerts epigenetic influences. We recently reported preliminary results on dietary acid load, methionine intake, and breast cancer risk. Therefore, both variables deserve further epidemiologic analysis. We revisited a Uruguay-based case-control study (572 cases/2,294 matched controls); women were recruited from 4 central hospitals, and all were interviewed using a specific questionnaire. Food-derived nutrients were calculated from available databases. Dietary acid load was estimated based on a validated formula: the potential renal acid load (PRAL) score. OR was estimated by logistic regression, adjusting for potential confounders. We found significant, direct associations between the breast cancer risk and PRAL (OR = 3.33) and methionine intake (OR = 5.87). Trends were significant (
