Genomic Resources and Annotations for a Colonial Ascidian, the Light-Bulb Sea Squirt Clavelina lepadiformis.
Article in Genome biology and evolution, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Ascidian embryos have been studied since the birth of experimental embryology at the end of the 19th century. They represent textbook examples of mosaic development characterized by a fast development with very few cells and invariant cleavage patterns and lineages. Ascidians belong to tunicates, the vertebrate sister group, and their study is essential to shed light on the emergence of vertebrates. Importantly, deciphering developmental gene regulatory networks has been carried out mostly in two of the three ascidian orders, Phlebobranchia and Stolidobranchia. To infer ancestral developmental programs in ascidians, it is thus essential to carry out molecular embryology in the third ascidian order, the Aplousobranchia. Here, we present genomic resources for the colonial aplousobranch Clavelina lepadiformis: a transcriptome produced from various embryonic stages, and an annotated genome. The assembly consists of 184 contigs making a total of 233.6 Mb with a N50 of 8.5 Mb and a L50 of 11. The 32,318 predicted genes capture 96.3% of BUSCO orthologs. We further show that these resources are suitable to study developmental gene expression and regulation in a comparative framework within ascidians. Additionally, they will prove valuable for evolutionary and ecological studies.
