Differences in Oral Health According to the Presence of Hearing Loss: Data from the 2021 Korea National Health and Nutrition Examination Survey.
Article in Noise & health. 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
backgroundThe prevalence of hearing loss is increasing annually and has a strong relationship with oral health. However, existing research on hearing loss is limited to children, making it necessary to expand the analysis to adults. Therefore, this study aims to identify differences in oral health-related factors according to hearing loss in adults over 40 years of age using the Korea National Health and Nutrition Examination Survey.
methodsThis study analyzed survey data from 2021. The study participants were divided into 1738 individuals in the nonhearing loss group and 1384 in the hearing loss group. Complex sample chi-square and complex sample independent t-tests were performed to determine differences in the sociodemographic characteristics, systemic diseases, hearing loss-related factors, and oral health status between the two groups.
resultsCompared to the nonhearing loss group, the hearing loss group was older and had lower income and education levels. In terms of oral health, the hearing loss group had fewer existing natural teeth, poorer prosthesis conditions, and a higher number of implants than the nonhearing loss group. The hearing loss group also experienced comparatively more problems with chewing and speaking (P < 0.05).
conclusionsIndividuals with hearing loss exhibited poorer oral health status than those without hearing loss. Therefore, dental professionals in clinical practice should develop their communication skills to interact effectively with patients with hearing loss and strive to improve their oral health.
