Near-Chromosomal-Level Genome Assembly of the Sea Urchin Echinometra lucunter, a Model for Speciation in the Sea.
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 5 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
Echinometra lucunter, the rock-boring sea urchin, is a widely distributed echinoid and a model for ecological studies of reproduction, responses to climate change, and speciation. We present a near chromosome-level genome assembly of E. lucunter, including 21 scaffolds larger than 10 Mb predicted to represent each of the chromosomes of the species. The 760.4 Mb assembly includes a scaffold N50 of 30.0 Mb and BUSCO (benchmarking universal single-copy orthologue) single copy and a duplicated score of 95.8% and 1.4%, respectively. Ab-initio gene model prediction and annotation with transcriptomic data constructed 33,989 gene models composing 50.4% of the assembly, including 37,036 transcripts. Repetitive elements make up approximately 39.6% of the assembly, and unresolved gap sequences are estimated to be 0.65%. Whole genome alignment with Echinometra sp. EZ revealed high synteny and conservation between the two species, further bolstering Echinometra as an emerging genus for comparative genomics studies. This genome assembly represents a high-quality genomic resource for future evolutionary and developmental studies of this species and more broadly of echinoderms.
