The mediating effect of depression on the association of hearing loss with all-cause and cardiovascular mortality: a prospective cohort study.

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
backgroundDepression has been hypothesized to act as a mediator linking hearing loss to mortality; however, existing evidence remains limited and inconsistent. We aimed to investigate the potential mediating role of depression on the association of hearing loss with all-cause and cardiovascular mortality using a large, nationally representative prospective cohort of the U.S. population.
methodsThis cohort study included 9,827 adults from the 2005–2018 National Health and Nutrition Examination Survey (NHANES). Multivariable Cox proportional hazards models were applied to examine the relationships of hearing loss and depression with all-cause and cardiovascular mortality. Multivariable linear regression was conducted to assess the link between hearing loss and depression. Mediation analysis was conducted to explore the mediating role of depression in the link between hearing loss and mortality outcomes.
resultsAfter adjusting for confounders, both hearing loss and depression showed positive associations with all-cause and cardiovascular mortality, as well as with each other. Mediation analyses revealed that depression mediated the associations between speech-frequency, low-frequency, and high-frequency hearing loss and all-cause mortality by 10.28%, 10.15%, and 9.27%, respectively. For cardiovascular mortality, depression accounted for 11.40%, 11.25%, and 11.67% of the associations, respectively. Significant and stable mediation effects were also observed across various hearing frequency ranges (0.5–8 kHz).
conclusionThese findings underscore the substantial impact of depression on all-cause and cardiovascular mortality risks in individuals with hearing loss. Integrating routine depression screening and targeted mental health interventions into hearing loss management strategies is crucial to mitigating mortality outcomes in this population.
