Mediating role of grip strength between depression symptoms and cognitive function: A cross-sectional study among older adults with diabetes in rural areas.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Older adults with diabetes are at an increased risk for both depression and cognitive decline. Depression symptoms have been linked to poorer cognitive function. Grip strength, an indicator of physical function, may play a role in this relationship. However, the specific mechanisms connecting depression, grip strength, and cognitive function in older adults with T2DM in rural areas are not fully understood. The objective of this study was to analyze the mediating role of grip strength in the relationship between depression symptoms and cognitive function. This Cross-sectional study was conducted from April to July 2023 in rural areas of China. To compare characteristics between male and female participants, one-way ANOVA and Chi-squared tests were used. Multivariate linear regression analysis was performed to examine the relationships between depression symptoms, grip strength, and cognitive function, adjusting for potential confounders. Bootstrap analysis, with 5000 resamples, was employed to assess the mediating role of grip strength in the relationship between depression symptoms and cognitive function. The study included 898 older adults with T2DM, with an average age of 69.73 years. Depression symptoms were found to be negatively associated with cognitive function. Grip strength was identified as a mediator in this relationship. Bootstrap analysis confirmed the partial mediating effect of grip strength, explaining 9% of the total effect of depression symptoms on cognitive function. These findings contribute to a better understanding of the underlying mechanisms between depression symptoms and cognitive function, elucidating the mediating role of grip strength in this association.
