The perception of Glass patterns by starlings (Sturnus vulgaris).
Article in Psychonomic bulletin & review, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Glass patterns are structured dot stimuli used to investigate the visual perception of global form. Studies have demonstrated that humans and pigeons differ in their processing of circular versus linearly organized Glass patterns. To test whether this comparative difference is characteristic of birds as a phylogenetic class, we investigated for the first time how a passerine (starlings, Sturnus vulgaris) discriminated multiple Glass patterns from random-dot stimuli in a simultaneous discrimination. By examining acquisition, steady-state performance, and the effects of diminishing global coherence, it was found that the perception of Glass patterns by 5 starlings differed from human perception and corresponded to that established with pigeons. This suggests an important difference in how birds and primates are specialized in their processing of circular visual patterns, perhaps related to face perception, or in how these highly visual animals direct attention to the global and local components of spatially separated form stimuli.
