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

In human language, word order impacts how words are categorized and understood (as nouns, verbs etc.). We have demonstrated that this effect extends to non-linguistic stimuli, suggesting that the impact of sequence order on stimulus categorization is a domain-general, rather than language-specific cognitive process. Here, we ask if this process is evolutionarily conserved in other non-human primates. We developed a non-linguistic experiment and tested rhesus macaques (
