Association of nutritional intake with myopia and astigmatism.
Article in Scientific reports, 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
This study investigates the association between dietary lutein and zeaxanthin intake and the prevalence of myopia and astigmatism using data from the NHANES 2007-2008 survey. A total of 3,759 participants aged 12-59 years were analyzed. Myopia was classified into emmetropia, low myopia, and high myopia based on spherical equivalent refraction (SER), while astigmatism was categorized into high, low, and moderate based on right eye cylinder degree. Nutrient intake data, including lutein and zeaxanthin, were analyzed alongside sociodemographic and eye refractive data. Statistical comparisons between groups were conducted using t-tests and chi-square tests. Among participants, 58.7% were emmetropia group, 34.0% had low myopia, and 7.4% had high myopia. For astigmatism, 5.9% had high, 82.2% had low, and 12.9% had moderate levels. Significant differences were observed in sociodemographic factors, refractive measurements, and keratometry parameters across myopia and astigmatism groups (P < 0.05). However, dietary lutein and zeaxanthin intake showed no significant differences among these groups (P > 0.05). This cross-sectional study found no significant association between lutein and zeaxanthin intake and the prevalence of myopia or astigmatism.
