Hidden colour signals as key drivers in the evolution of anti-predator coloration and defensive behaviours in snakes.

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
The initial evolution of warning coloration ("aposematism") within a cryptic population of defended prey presents an evolutionary paradox. A recent phylogenetic analysis of amphibia suggests a new solution: prey that combine cryptic colours with conspicuous patches on concealed body parts ("hidden signallers"), may have mediated the transition of species from camouflage to aposematism. Here, we focus on the colour-diverse snake family Elapidae and test whether species with hidden colours could also serve as an intermediate stage in the evolution of aposematism in this group. Phylogenetic comparative analysis reveals several key patterns in their anti-predator colour evolution: (i) a few major transitions influenced the overall distribution of hidden-colours, camouflage, and aposematism in the group, and (ii) aposematism evolved multiple times, with hidden coloration a common precursory state, while direct transitions from camouflage to aposematism are also observed. We also quantify associations between colour patterns and defensive behaviours that reveal ventral surfaces (i.e. hidden signals). We find that venter-revealing defensive behaviours frequently co-occur with hidden colour signals. Our results suggest that aposematism can evolve through multiple routes and highlight the prevalence of co-evolution between venter-revealing defensive behaviour and anti-predator coloration in snakes.
