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

Objective: Systematically evaluate the acute effects of anodal transcranial direct current stimulation (a-tDCS) on athletes' sport-specific performance and identify the optimal stimulation parameters and target brain regions for enhancing sport-specific performance. Methods: Search PubMed, Web of Science, CNKI, Wanfang, and other databases to include randomized controlled trials studying the effects of anodal tDCS on sports performance in healthy athletes. Use a random-effects model to calculate the standardized mean difference (SMD), assess heterogeneity, and evaluate influencing factors. Additionally, conduct three subgroup analyses: (1) based on stimulated brain areas (M1, PFC, TC, CB); (2) based on different sports performance domains (endurance, strength, precision skill tasks, competitive-collaborative skills) for cluster analysis; (3) tDCS protocol parameters (current intensity and stimulation duration). Results: This study included 31 articles, covering 473 athletes. The meta-analysis results showed that the acute effect of a-tDCS significantly improved athletes' specific sports performance, with a moderate effect size (SMD = 0.39, 95% CI = 0.23-0.54, p < 0.001). Subgroup analysis revealed that M1 stimulation had the most consistent effect (SMD = 0.32, 95% CI = 0.15-0.48, p < 0.001), followed by PFC stimulation (SMD = 0.39, 95% CI = 0.03-0.76, p = 0.03). a-tDCS significantly enhanced athletes' endurance performance (SMD = 0.46, 95% CI = 0.20-0.72, p < 0.001) and competitive-collaborative skill tasks (SMD = 0.45, 95% CI = 0.10-0.80, p = 0.01). Analysis of stimulation parameters indicated that a moderate current intensity of 1.6-2.0 mA (SMD = 0.38, p < 0.001) and a stimulation duration of 16-20 min (SMD = 0.45, p < 0.001) were the optimal protocols for enhancing sports performance. Conclusion: The acute effects of a-tDCS significantly enhance athletes' endurance and competitive-collaborative skill performance, particularly when targeting the M1 and PFC regions. The optimal stimulation protocol involves a moderate current intensity (1.6-2.0 mA) and duration (16-20 min). Future research should further optimize stimulation parameters and explore long-term effects to enhance the application of a-tDCS in sports training.
