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

Dance interventions improve limb motor function in Parkinson's disease (PD), yet their impact on speech-related motor control and overall language (e.g., semantics) remains unexplored. To test this, we conducted a 12-week exploratory clinical trial comparing Amazonian dance (two groups: north and south) with a matched-physical intensity control (Nordic walking) and ran automated speech and language analysis pre- and post-intervention. The clearest corrected effect was in the dance north group, who showed improvement in prosody (main tone) compared with Nordic walking. We observed additional consistent signals (uncorrected) for prosody and semantic organization (granularity), particularly when both dance groups were pooled relative to the Nordic walking group. These findings were further supported by subject-level consistency and covariate-adjusted analyses. Our exploratory study suggests that dance may enhance speech-motor and language functions in PD, potentially through auditory-motor coupling, improved timing, and the engagement of overlapping neural substrates between dance and speech and/or language.
