Hearing and Cognitive Function in Aged Adults: A Machine Learning and Mediation Analysis of NHANES.
Article in World journal of otorhinolaryngology - head and neck surgery, 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
Objective: Cognitive impairment is a major public health challenge. Early identification is crucial, especially in the often-overlooked 60-69 age group. This study developed an efficient risk identification tool. Methods: Using data from the US National Health and Nutrition Examination Survey (NHANES), three machine learning algorithms screened for key predictive features. Eight models were combined with a nomogram. Mediation, restricted cubic spline, and dose-response analyses explored the hearing-cognition relationship among older adults in the United States. Results: Five key features including race, education, alcohol consumption, pure tone audiometry (PTA), and systemic inflammation response index (SIRI) were identified. The random forest model performed best (area under the curve, AUC = 0.865). Education, race, and PTA were the top three contributors. A significant positive linear relationship existed between PTA and cognitive risk, with each 1 dB HL increase raising the risk by 2%. The nomogram highlighted the highest risk for those with less than ninth-grade education, Hispanic ethnicity, and high PTA. Conclusion: A exploratory risk stratification tool is developed. Education, race, and hearing level are key contributing variable. The linear PTA-cognition relationship suggests hearing screening may aid in early risk stratification for cognitive impairment.
