Shared competence forms the basis of gill arch and paired fin serial homology.

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 origin of paired fins is an unresolved controversy in vertebrate evolutionary biology. Karl Gegenbaur famously proposed that paired fins evolved by the transformation of a gill arch, but this hypothesis remains largely unsupported by the fossil record. Also, seemingly at odds with gill arch-paired fin serial homology are their distinct embryonic origins from neural crest and lateral plate mesoderm, respectively. We have previously shown that skate gill arch skeletal elements may derive solely from neural crest, or from a mixture of neural crest and mesoderm, and we have shown that skate gill arches and jawed vertebrate fins/limbs share several molecular patterning mechanisms. Here, we show in the little skate (
