Physical disorders, ADLs, cognition, and depression in nursing home residents: a parallel mediation analysis.

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
objectiveThis study aimed to explore the relationships between physical disorders (visual impairment, hearing impairment, and chewing impairment) and depression among older adults in nursing homes in one city of China, and to examine the parallel mediating roles of activities of daily living (ADLs) and cognition.
methodsThe study conducted a cross-sectional study involving 591 older adults from 50 nursing homes in China. Participants provided informations on their vision, hearing, and chewing. Cognition was assessed using tests of memory and thinking skills. ADLs were evaluated through measures of daily task performance, and depression was assessed by epidemiologic studies depression scale. Multiple linear regression analysis and PROCESS macro were used for data analysis.
resultsThe overall detection rate of depression was 28.43%, and significant correlations were observed among physical disorders, ADLs, cognition, and depression (p < 0.05). Mediation analysis revealed that hearing impairment not only had a direct effect on depression (β = 2.298, p < 0.001) but also significant indirect effects mediated through ADLs (β = 0.630, p < 0.01) and cognition (β = 0.666, p < 0.001). The total indirect effect accounted for 36.06% of the total effect. Similarly, the effects of visual impairment on depression were mediated by ADLs (β = 0.301, p < 0.05) and cognition (β = 0.380, p < 0.01), with the mediation effect accounting for 68.10%. In contrast, chewing impairment showed a direct effect on depression (β = 1.354, p < 0.01), but no significant mediation was found through ADLs and cognition.
conclusionsOur findings indicated that hearing and visual impairments were associated with an increased risk of depression, with these effects operating both indirectly through ADLs and cognition. These findings highlight the necessity of comprehensive geriatric care approaches that integrating sensory rehabilitation with interventions with ADLs and cognitive support.
