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: Middle-aged and older adults with type 2 diabetes mellitus (T2DM) often experience insufficient physical activity (PA) and reduced quality of life (QOL). Understanding how psychosocial factors are associated with this relationship is important for developing effective nursing interventions. Therefore, this study aimed to investigate the mediating roles of psychological resilience and exercise self-efficacy in the association between PA and QOL among community-dwelling populations. Methods: A cross-sectional survey was conducted among 328 middle-aged and older adults (≥ 45 years old) with T2DM in Changsha, China. Data were collected using validated instruments, including the International Physical Activity Questionnaire (IPAQ-SF), Connor-Davidson Resilience Scale (CD-RISC), Exercise Self-Efficacy Scale, and the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36). Structural equation modeling and 5,000-bootstrap resampling were used to test mediation effects. Results: Given the high collinearity observed between physical activity and exercise self-efficacy in the partial mediation model, a full mediation model was retained as the final model. PA was indirectly and positively associated with QOL primarily through exercise self-efficacy (standardized indirect effect = 0.195, 95% CI [0.103, 0.287]). The sequential pathway through psychological resilience and exercise self-efficacy was also significant (standardized indirect effect = 0.009, 95% CI [0.002, 0.017]), whereas psychological resilience alone was not a significant mediator. The final model demonstrated acceptable fit (χ²/df = 3.26, RMSEA = 0.083, CFI = 0.960, NFI = 0.944, IFI = 0.961, TLI = 0.920). Conclusions: This study tested a chain mediation model suggesting that the observed association between PA and QOL may be partly explained by a sequential psychosocial pathway involving psychological resilience and exercise self-efficacy. These findings highlight the potential value of integrating psychological empowerment and behavioral strategies in future interventions aimed at supporting better QOL among middle-aged and older adults with T2DM.
