Side bias behaviour in dogs (Canis familiaris) is influenced by task complexity.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Side bias is often reported in canine cognition experiments when dogs' behaviour is tested in two-way choice tasks. Recently it has been proposed that side bias, which remains consistent over time and across different situations, may parallel a human psychiatric condition known as visual neglect. Here we tested an additional factor that could contribute to the development of side bias behaviour in dogs: task complexity. Subjects were tested in a series of two-way choice tasks of varying difficulty and the proportion of subjects showing side bias was compared across these tasks. Results showed that dogs were more likely to develop side bias in more complex situations, such as the food preference task, or in more unusual tasks, such as elbow pointing, compared to simpler tasks like sustained pointing. This suggests that, as expected, task complexity contributes to dogs' side bias, with side preference potentially being at least partly triggered by more challenging tasks that yield decreased reward.
