Comments on "Intra- and interspecific variation in self-control capacities of parrots in a delay of gratification task".
Article in Animal cognition, 2022. 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
Brucks (Anim Cogn 25(2):473-491, 2021) have published an intriguing paper on the differing abilities of various species of parrots to succeed in a delay of gratification task. I find their interspecies comparisons of considerable interest but take exception to their misrepresentation of prior research on delayed gratification from our laboratory in Koepke (J Comp Psychol 129:339-346, 2015). Contrary to their claims, our subject was never trained on the task; rather, one might argue instead that all their subjects received considerable training or at least forms of pre-exposure that could affect their overall claims. I also briefly discuss other design features that may have affected their results.
