1 · What the graph read from it

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.

2 · The registry

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

objectiveTo compare the effects of exercise modalities on sleep quality in individuals with breast cancer, and to examine dose-response associations between exercise dose and sleep improvement.

methodsPubMed, Web of Science, Embase, the Cochrane Library, and EBSCO were searched from inception to March 2026. Risk of bias was assessed using RoB 2. Bayesian multilevel network meta-analysis compared exercise modalities against active controls. Meta-regression and nonlinear dose-response analyses explored effect modifiers and dose-response patterns.

resultsThirty-nine randomized controlled trials involving 4066 participants were included. Compared with active controls, Tai Chi/Qigong showed the largest sleep benefit (Hedges' g = -0.45, 95% CrI: -0.86 to -0.04), followed by yoga and combined exercise (COM; both g = -0.30). Aerobic exercise suggested possible benefit but with uncertainty, whereas resistance training, dance, and stretching showed no clear advantage. Dose-response analyses suggested greater benefits around potentially beneficial moderate-dose ranges, with exploratory estimated values of approximately 4.5 METs, 281.3 MET·min/session, and 910 MET·min/week. Higher baseline Pittsburgh Sleep Quality Index scores were associated with greater sleep improvement.

conclusionsTai Chi/Qigong, yoga, and COM may be promising exercise modalities for improving sleep quality in this population. Exercise-related sleep benefits may occur within a moderate dose window. Given the very low certainty of evidence and limited head-to-head comparisons, these findings should be interpreted cautiously and confirmed by high-quality randomized controlled trials.
