Hearing loss and executive functions - results from a population-based cohort study.
Article in PloS one, 2026. 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
introductionHearing loss is linked to cognitive decline, yet its relation to specific executive functions remains unclear. This study examines associations between planning ability, pure-tone audiometry and speech-in-noise performance.
methodsData were drawn from the Gutenberg Health Study (GHS), a large population-based cohort at the University Medical Center Mainz. Participants with complete pure-tone audiometry and planning ability data were included (N = 4,458; 2,314 males (51.9%), 2,144 (48.1%) females; mean age 58.0 ± 10.1 years, range 40-80). Audiologic testing included air- and bone-conduction pure-tone audiometry; hearing impairment was defined by WHO threshold. Speech-in-noise perception was measured using the German Matrix Test "Oldenburg Satztest". Planning ability was assessed using the Freiburg version of the Tower of London. Associations were analyzed with linear and logistic regression.
resultsHearing loss (HL ≥ 20 dB; both ears) revealed a significant negative association with planning ability total score (β = -0.346, p < 0.01), but not significantly with clinical executive dysfunction (<16. Percentile total TOL) (OR=1.109, p = 0.43). Higher planning ability reduced the likelihood of hearing impairment (OR=0.97, p = 0.006) and was linked to better speech-in-noise perception (lower OLSA SRT, β = -0.035, p = 0.001).
conclusionHearing loss is linked to reduced planning ability, while higher planning ability decreases the likelihood of hearing impairment and increased speech perception in noise. These findings support models proposing that hearing loss imposes additional demands on working memory and attention. Longitudinal studies are needed to clarify causal directions and the potential role of interventions.
