Functional trait network analysis in birds.
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 1 paper.
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
Functional traits are those whose variation affects fitness. We compared the interdependence of beak and postcranial functional morphological traits across birds with different lifestyle strategies and trophic niches to identify those traits that drive major phenotypic changes, and tested for differences in modular organization and integration among groups. Body mass consistently emerged as influencing all other traits. We found a lower integration in aquatic birds, although this may mask the presence of distinct morphotypes. Integration is highest in vertivore birds, revealing constraints imposed by the feeding habit. Overall, phenotypes were more modular according to their trophic niches, and beak and postcranial traits were distributed in unexpected patterns among modules. The ability of functional traits to evolve independently appears to be a necessary condition for specialization.
