Sensorimotor numerosity uniquely supports arithmetic development in children.
Article in i-Perception. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Symbolic numerical thinking is a signature human cognition, yet its foundations remain unclear. The prevailing perspective holds that numerical abilities build on a non-symbolic visual number sense that extracts numerosity from the environment. However, recent evidence suggests a sensorimotor number system also tracks the numerosity of internally self-generated actions. Whether this system supports the development of mathematical skills is unknown. In a series of psychophysical tasks, we measured precision (Weber fraction) for estimating, without counting, the number of (i) self-generated hand actions, (ii) visual-temporal flashes, and (iii) dot ensembles. Precision in the action-based numerosity estimation task explained about 30% of the variance in mental calculation ability - three and 15 times higher than spatial and temporal visual numerosity, respectively. This link remained strong even after regressing out the variance explained by natural development (age), verbal and non-verbal reasoning, non-numerical motor abilities, and visual numerosity estimation precision (R
