Expanding on Our Knowledge of Ecdysozoan Genomes: A Contiguous Assembly of the Meiofaunal Priapulan Tubiluchus corallicola.
Article in Genome biology and evolution, 2023. 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
Genomic data for priapulans are limited to a single species, restricting broad comparative analyses and thorough interrogation of questions spanning phylogenomics, ecdysozoan physiology, and development. To help fill this void, we present here a high-quality priapulan genome for the meiofaunal species Tubiluchus corallicola. Our assembly combines Nanopore and Illumina sequencing technologies and makes use of a whole-genome amplification, to generate enough DNA to sequence this small meiofaunal species. We generated a moderately contiguous assembly (2,547 scaffolds), with a high level of completeness (metazoan BUSCOs n = 954, single-copy complete = 89.6%, duplicated = 3.9%, fragmented = 3.5%, and missing = 3.0%). We then screened the genome for homologs of the Halloween genes, key genes implicated in the ecdysis (molting) pathway of arthropods, recovering a putative homolog of shadow. The presence of a shadow ortholog in two priapulan genomes suggests that the Halloween genes may not have evolved in a stepwise manner in Panarthropoda, as previously thought, but may have a deeper origin at the base of Ecdysozoa.
