Combined effect of anemia and chronic rhinitis on hearing loss in Korean adults: a nationwide observational study.
Observational study in Epidemiology and health, 2024. 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
objectivesStudies have suggested an association between hearing loss and anemia. Hearing loss has also been linked to rhinitis, which is characterized by inflammation of the nasal mucous membranes and sinus mucosa. Few studies have concurrently explored the relationships between hearing loss, anemia, and rhinitis. This study was conducted to investigate the association between hearing loss and anemia and to further analyze the potential role of rhinitis in this relationship.
methodsData were collected from the 2020 Korea National Health and Nutrition Examination Survey. Hearing loss was measured with an audiometer in a soundproof booth and was defined as at least moderate impairment (as indicated by a pure-tone average of ≥41 dB in the better-hearing ear). The association between hearing loss and anemia was analyzed using multivariable logistic regression. The combined effect of anemia and rhinitis on hearing loss was assessed with an interaction term.
resultsAmong the 2,772 participants, 477 (17.2%) exhibited hearing loss. Participants with anemia were more likely to experience hearing loss than those without anemia (odds ratio [OR], 1.58; 95% confidence interval [CI], 1.07 to 2.33). Furthermore, the odds of hearing loss were greater in participants with both anemia and rhinitis (OR, 3.79; 95% CI, 1.93 to 7.43) relative to those without either condition.
conclusionsAnemia was associated with hearing loss in individuals aged 40 years and older. Based on the analysis of combined effects, participants with anemia and chronic rhinitis were more likely to experience hearing loss than individuals without these conditions.
