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 investigate which brain activity frequency of electroencephalogram (EEG)-neurofeedback training (NFT) was the most effective for enhancing working memory (WM) and episodic memory (EM) in healthy participants through network meta-analysis (NMA).

methodsSearched PubMed, Embase, and Cochrane Library for studies published from January 1990 to January 2025. We performed Bayesian NMA, pooling continuous outcome data using the standardized mean difference effect size (ES). Global and local evaluations of inconsistency were conducted using the chi-square test, side-splitting, and loop-specific approaches. A consistency model was applied and the global approach to inconsistency showed no significance. Efficacy ranks were determined using the surface under the cumulative ranking curve (SUCRA) for each intervention. Publication bias was assessed using the comparison-adjusted funnel plot and Egger's test. Finally, sensitivity analysis confirmed our findings' robustness.

resultsSixty studies were included, comprising 50 trials on WM and 24 trials on EM. While the global inconsistency analysis showed no significant inconsistency for WM (χ

conclusionThrough NMA, alpha activity (7-13 Hz) may be a crucial frequency impacting memory. Brain activity combined with other training methods requires more robust studies for future investigation. This study registered with www.crd.york.ac.uk/prospero/ (CRD42024539656).
