Hearing Status, Social Engagement, and Longitudinal Changes in Cognition: Results From the Mexican Health and Aging Study.
Article in Journal of aging research, 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
Objectives: This study explored the mediation and moderation effects of social engagement on the relationship between hearing status and cognitive function among Mexican adults aged ≥ 50 years across a six-year period (2015-2021). Methods: Data were drawn from the nationally representative Mexican Health and Aging Study (MHAS). Social engagement was calculated by summing the number of social activities and frequencies undertaken in the past year. A global measure of cognitive function was derived by summing Results: There were 10,561 people in the analytic sample. Greater social engagement was independently associated with better cognitive function over time. Better hearing status was associated with higher cognitive functioning in the following survey wave. Fair or better hearing was significantly associated with increased social engagement. The association was attenuated when covariates were adjusted. The association between hearing difficulty and cognitive function varied across levels of social engagement. Discussion: The mediation and moderation effects of social engagement on the association between hearing difficulty and cognitive function were affected by the population's socioeconomic status among middle-aged and older adults in Mexico. Future research should investigate other unknown mediators between hearing difficulty and cognitive health of middle-aged and older adults in low- and middle-income countries.
