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

Developmental dyslexia involves deficits in phonological awareness and cortical connectivity, yet the effects of binaural beats on these domains remain underexplored. This study examined the effects of theta (5 Hz) and beta (15 Hz) binaural beats on phonological processing and EEG coherence in 45 dyslexic children aged 6.5-8.3 years. Participants were assigned to the theta, beta, or control condition and received 12 binaural beat sessions over a period of four weeks. Resting-state EEGs were recorded at baseline, after the binaural beats sessions, and at a 6-week follow-up. Results showed that theta binaural beats significantly enhanced intrahemispheric coherence in frontal and temporal regions, correlating with improved phonological awareness. Beta beats enhanced interhemispheric coherence, particularly between temporal lobes, potentially supporting phonological decoding. The control group showed no significant changes. Correlation analysis revealed that coherence in specific brain regions (e.g., T3-T4, r = 0.788, p = 0.0013) was significantly associated with performance on phoneme judgment tasks. These findings suggest that frequency-specific binaural beats can enhance neural connectivity and phonological processing. This non-invasive approach shows potential for further exploration of cognitive effects in dyslexic children, though limitations such as small sample size and restricted frequency range necessitate additional research.
