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
Objective: Physical exercise is an important health-promoting behavior for older adults, while depressive symptoms are a major psychological factor affecting their quality of life and active aging. This study aimed to examine the associations between physical exercise and depressive symptoms among older adults and to further explore the potential indirect pathways involving self-rated health and subjective wellbeing. Methods: Using data from the 2023 Chinese General Social Survey (CGSS), a total of 2,233 older adults aged 60 years and above were included in the analysis. Multiple linear regression and serial mediation analyses were conducted using the PROCESS macro in SPSS. Bootstrap sampling with 5,000 resamples was applied to test the significance of the mediating effects. Results: Physical exercise was significantly and negatively associated with depressive symptoms among older adults, indicating that higher frequencies of exercise participation were associated with lower levels of depressive symptoms. In addition, physical exercise showed significant indirect associations with depressive symptoms through self-rated health (indirect effect = 40.5%) and subjective wellbeing (indirect effect = 9.7%), as well as through the serial pathway of "self-rated health → subjective wellbeing" (indirect effect = 3.8%). The total indirect effect (54%) was larger than the direct effect (46%), suggesting that a substantial proportion of the observed association between physical exercise and depressive symptoms was statistically accounted for by the indirect pathways examined in the model. Conclusion: Higher frequency of physical exercise was associated with lower levels of depressive symptoms among older adults, both directly and indirectly through self-rated health and subjective wellbeing. These findings highlight the potential relevance of physical exercise, self-rated health, and subjective wellbeing to mental health and active aging among older adults. Policies and interventions may consider strengthening support systems for older adults' participation in physical exercise, while simultaneously addressing both physical and psychological wellbeing.
