β-catenin-driven endomesoderm specification is a Bilateria-specific novelty.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Endomesoderm specification by a maternal β-catenin signal and body axis patterning by interpreting a gradient of zygotic Wnt/β-catenin signalling was suggested to predate the split between Bilateria and their sister clade Cnidaria. However, in Cnidaria, the roles of β-catenin signalling in these processes have not been demonstrated directly. Here, by tagging the endogenous β-catenin in the cnidarian Nematostella vectensis, we confirm that its oral-aboral axis is indeed patterned by a gradient of β-catenin signalling. Strikingly, we show that, in contrast to bilaterians, Nematostella endomesoderm specification is repressed by β-catenin and takes place in the maternal nuclear β-catenin-negative part of the embryo. This completely changes the accepted paradigm and suggests that β-catenin-dependent endomesoderm specification was a bilaterian innovation linking endomesoderm specification to the subsequent posterior-anterior patterning.
