Comparative effects of exercise modalities on sleep quality in middle-aged and older adults with sleep disorders: A systematic review with pairwise, network, and dose-responsemeta-analyses.
Review in Journal of exercise science and fitness, 2026. 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
Background: Exercise may improve sleep quality in middle-aged and older adults with sleep disorders, but the comparative effects of different exercise modalities and the dose-response relationship remain unclear. Methods: We systematically searched PubMed, Web of Science, Embase, and the Cochrane Library from inception to May 2026. Eligible studies were randomized controlled trials examining the effects of exercise interventions on sleep quality in middle-aged and older adults with sleep disorders. Two independent reviewers assessed study quality, and random-effects pairwise, network, and dose-response meta-analyses were performed to evaluate the effects of different exercise interventions and doses on sleep quality. Results: The analysis included 23 randomized controlled trials involving 1,478 middle-aged and older adults with sleep disorders. Pairwise meta-analysis showed that exercise reduced Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) scores but had no significant effect on Epworth Sleepiness Scale (ESS) scores. Bayesian network meta-analysis showed that, compared with the control group, aerobic exercise (SMD = 1.34, 95% CrI: 0.86∼1.82), mind-body exercise (SMD = 0.64, 95% CrI: 0.30∼0.97), and combined exercise (SMD = 0.60, 95% CrI: 0.13∼1.07) may improve PSQI scores. The dose-response analysis suggested an inverted U-shaped association, with the largest predicted effect occurring near 539 MET-min/week within the observed dose range. Conclusions: Low-to moderate-certainty evidence suggests that aerobic, mind-body, and combined exercise may reduce PSQI scores, with a nonlinear dose-response relationship.
