The association between macronutrients intake and myopia risk: a systematic review and meta-analysis.
Synthesis in BMC ophthalmology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundDietary factors have been suggested as potential risk factors for myopia, but research findings on this relationship are inconclusive. The potential predisposing or protective role of macronutrient (carbohydrate, protein, fat) intake in the development of myopia was systematically reviewed, followed by data synthesis by meta-analysis.
methodsA systematic search was conducted in PubMed, Web of Science, Scopus, and Google Scholar up to the end of June 2023 to identify all relevant studies. All observational studies that assessed the relationship between macronutrient intake with myopia, axial length (AL) of eyes and spherical equivalent refractive error (SE) on individuals younger than 18 years old were included.
resultsAfter removing duplicates and screening studies, four studies were included in the systematic review and meta-analysis. Pooled odds ratios regarding the association between myopia development and nutritional intake were 1.01 (95% CI: 0.94, 1.08), 0.97 (95% CI: 0.86, 1.08), and 0.99 (95% CI: 0.83, 1.18) for carbohydrates, proteins, and fats, respectively, indicating no significant associations. Intake of carbohydrates, proteins, and fats was not significantly associated with either SE or AL.
conclusionsIntake of carbohydrates, fats, or proteins did not influence the risk of myopia. The relationship between the intake of other macronutrients and myopia is suggested to be scrutinized in future studies. REGISTRATION: The systematic review protocol was registered on PROSPERO (registration number: CRD42024541369).
