Effects of Aerobic Exercises at Different Intensities on Sleep Quality in Individuals with Depression: A Systematic Review and Meta-Analysis.
Review in Nature and science of sleep, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Depression patients frequently report sleep disorder. Aerobic exercise is believed to improve sleep quality, but its effect on the overall sleep of depressed patients remains uncertain. This study systematically evaluates the effects of aerobic exercises at different intensities on subjective and objective sleep quality in participants diagnosed with depression or at high risk of depression, from studies covering various depression subtypes (including but not limited to geriatric depression, prenatal depression, and poststroke depression), and examines changes in depression, anxiety, and quality of life following aerobic exercise. Methods: Systematic searches for randomized controlled trials on aerobic exercise, depression, and sleep quality were conducted using PubMed, Web of Science, Embase, and the Cochrane Library up to December 31, 2024. Meta-analysis was performed using Review Manager 5.4.1 and stata 17.0. Results: In total, 13 trials (n = 994) were included. Aerobic exercise significantly improved subjective sleep quality [SMD = -0.52, 95% CI = (-0.66, -0.38)] but had no significant effect on objectively measured sleep efficiency [SMD = -0.14, 95% CI = (-0.46, 0.75)], total sleep time [SMD = 0.30, 95% CI = (-0.03, 0.62)], or sleep latency [SMD = -0.11, 95% CI = (-0.76, 0.54)]. Additionally, aerobic exercise significantly alleviated depression [SMD = -0.70, 95% CI = (-0.93, -0.47)] and anxiety [SMD = -0.47, 95% CI = (-0.74, -0.19)], and enhanced quality of life [SMD = 0.64, 95% CI = (0.36, 0.92)]. Subgroup analyses revealed no significant differences among the different intensities. Conclusion: Aerobic exercise significantly improves subjective sleep quality, alleviates depressive and anxiety symptoms, and enhances quality of life in depression patients. Light-, moderate-, and vigorous-intensities aerobic exercises have equal positive effects on these indicators. Given the bidirectional relationship between sleep disturbances and depression progression, this study highlights the potential of exercise therapy to disrupt the vicious cycle.
