Effectiveness in Preventing Hearing Loss: Meta-Analysis of Dietary Consumption Studies.
Article in American journal of lifestyle medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveThe systematic review with meta-analysis aimed to verify the occurrence of a protective effect on hearing loss due to a higher intake of carotenoids, vitamins A, C, E, and folate present in diets.
methodsThe search for scientific articles was carried out by 2 independent researchers in electronic databases. Meta-analysis was performed by constructing summary risk measures for each vitamin or antioxidant, combining the risk ratios or adjusted odds ratios (OR) for the various variables observed in the highest categories of vitamin or antioxidant consumption.
resultsFive studies involving an estimated 100 549 participants were included in the quantitative synthesis. The summary measures calculated for the highest quartiles/quintiles of the studies were Hazard ratios (HR) .990 for vitamin C; HR 1.07 and OR .925 for vitamin E; HR .921 for folate and OR .906 for vitamin A.
conclusionDietary intake of vitamins and antioxidants was inversely associated with the risk of developing hearing loss. Individuals with a higher intake of antioxidants may have better hearing thresholds, especially with the intake of β-carotene.
