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
Background: Emerging research indicates a possible link between marital status and cognitive performance among elderly individuals, yet limited investigations have explored the potential mediating effects of depressive symptoms within this association. Objective: The present study aimed to examine the intermediary function of depressive symptoms in the connection between marital status and cognitive abilities within China's aging population. Methods: The data for this study were obtained from the 2015 CHARLS survey wave, which included 5671 elderly people aged ≥60 years. To assess the associations among marital status, cognitive performance, and depressive symptoms, we employed linear regression modeling. Subsequently, mediation analysis was conducted to investigate whether depressive symptoms might serve as an intermediary factor in the connection between marital status and cognitive functioning. Subgroup analyses were performed according to marital status, sex, residential area, and education in order to evaluate the robustness and heterogeneity of the mediation effect. Results: The findings indicated that marital status was positively associated with cognitive function in the elderly (β = 0.49, 95% CI: 0.17, 0.81, p = 0.0023), with married individuals demonstrating superior cognitive function. Depressive symptoms accounted for approximately 27.39% of the total effect of the correlation between marital status and cognitive impairment (95% CI: 14.16%, 79.68%, p = 0.002). Conclusions: Our research indicates that depressive symptoms serve as a mediating factor in the relationship between marital status and cognitive function in aging populations. Older adults with cognitive impairment should be assessed for their marital status, and early identification and intervention for depressive symptoms are recommended.
