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
Purpose: To examine cross-sectional associations between physical exercise, quality of life (QoL), and sleep quality in perimenopausal women, and identify other key correlates. Methods: This single-center cross-sectional study recruited 457 perimenopausal women (convenience sampling) from the Second Qilu Hospital of Shandong University (Jinan, China) between January 2022 and October 2025. Assessments included Kupperman Menopausal Index (KMI), MENQOL, PSQI, and IPAQ-L. Women reporting regular moderate-to-vigorous exercise (≥3 times/week, ≥30 min/session) formed the exercise group (n=279); others formed the non-exercise group (n=178). Spearman correlation and multiple linear regression were used. Results: The exercise group had significantly lower (better) KMI, MENQOL, and PSQI scores (all P<0.05). Exercise showed small negative correlations with PSQI and MENQOL (r=-0.102 to -0.157). After adjusting for monthly income, regression showed that higher KMI, higher PSQI, and lower education were independently associated with poorer QoL; coronary heart disease (low prevalence) was also associated with poorer QoL, whereas other economic sources were associated with better QoL (adjusted R Conclusion: Regular exercise was associated with better QoL and sleep quality, partly explained by less severe menopausal symptoms. However, causality cannot be inferred, and effect sizes were small (|r|<0.2), likely below minimal clinically important differences. Exercise is one contributing factor among many. Limitations include cross-sectional design, self-reported data, convenience sampling, and low coronary heart disease prevalence. Clinical Trial Number: Not applicable (observational study).
