Color polymorphic carnivores have faster speciation rates.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Variation in coat color is a prominent feature in carnivores, thought to be shaped by environmental factors. As new traits could allow populations to occupy novel niches and habitats, color polymorphism may be maintained by balancing selection. Consequently, color polymorphic species may speciate more rapidly and can give rise to monomorphic daughter species. We thus predicted that, within the Carnivora, (i) speciation rate is higher in polymorphic lineages, (ii) divergence between color polymorphic lineages is more recent, and (iii) within closely related groups, polymorphic lineages are ancestral and monomorphic lineages derived. We also tested whether accelerated speciation rates relate to niche breadth, measured by the number of occupied habitats and range size. We collected data of 48 polymorphic and 192 monomorphic carnivore species, and assessed speciation rates using phylogenetic comparative methods. We found that polymorphic carnivores had higher speciation rates (λ
