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

This study examined the understanding of cardinality and conservation in children with and without autism (aged 4-7 years, without intellectual disability), and its relation to counting strategies. A total of 82 children participated in the study, including 41 autistic children (36 boys, 5 girls) and 41 age- and sex-matched non-autistic peers. While both groups demonstrated similar mastery of cardinality, autistic children showed lower performance in conservation tasks. Response times were longer in autistic children during counting tasks. Concerning counting strategies, autistic children relied more on verbal counting with pointing (VCP) and used the rapid recognition strategy (N) less frequently, even for small canonical sets. While both strategies (N and VCP) supported cardinality in both autistic and non-autistic children, only the N strategy appeared closely linked to successful conservation performance. These findings highlight two areas of relative difficulty for some autistic children and point to the potential of targeted interventions to strengthen foundational numerical skills and support later mathematical development.
