Female Black-Capped Chickadees (
Article in Ecology and evolution, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Group living provides many potential benefits but can also incur important costs via competition for access to resources. Even in the absence of resource depletion, interference competition can reduce access to resources, and interference competition is not expected to affect all group members equally. In groups with dominance hierarchies, dominant individuals have priority access to resources and are therefore expected to experience lower costs of interference competition compared to subordinate individuals. Here, we assessed the effect of manipulating the number of feeders available with ad libitum food, which we assumed would affect competition intensity, on total daily feeder visits in a marked population of 126 black-capped chickadees (
