Effects of exercise interventions on EEG alpha power across different populations: a systematic review and meta-analysis.
Synthesis in Frontiers in psychology, 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
Objective: The objective of this study was to systematically evaluate the to evaluate the effects of exercise interventions on electroencephalogram (EEG) alpha-band power across different populations. Methods: PubMed, Embase, Scopus, the Cochrane Library, and Web of Science were searched from inception to June 25, 2026. Randomized controlled trials comparing an exercise intervention with a control condition and reporting EEG alpha-band power were included. Standardized mean differences were calculated as Hedges' g. Random-effects models using restricted maximum likelihood estimation and Knapp-Hartung adjustment were applied. Heterogeneity, prediction intervals, subgroup effects, intervention-duration meta-regression, influence diagnostics, recording-condition sensitivity analyses, and small-study effects were examined. Results: Thirteen randomized controlled trials involving 497 participants were included. Exercise interventions were associated with greater EEG alpha-band power than control conditions (Hedges' g = 1.23, 95% CI [0.44, 2.02], Conclusion: Exercise interventions were associated with greater EEG alpha-band power on average; however, the considerable heterogeneity and prediction interval crossing the null indicate substantial uncertainty across study settings.
