Chromosome-Level Genome Assembly of the Butter Clam Saxidomus purpuratus.
Article in Genome biology and evolution, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Herein, we provide the first whole-genome sequence of the purple butter clam (Saxidomus purpuratus), an economically important bivalve shellfish. Specifically, we sequenced and de novo assembled the genome of Sa. purpuratus based on PromethION long reads and Hi-C data. The 978-Mb genome of Sa. purpuratus comprises 19 chromosomes with 36,591 predicted protein-coding genes. The N50 length of Sa. purpuratus genome is 52 Mb, showing the highest continuous assembly among bivalve genomes. The Benchmarking by Universal Single-Copy Orthologs assessment indicated that 95.07% of complete metazoan universal single-copy orthologs (n = 954) were present in the assembly. Approximately 51% of Sa. purpuratus genome comprises repetitive sequences. Based on the high-quality Sa. purpuratus genome, we resolved half of the immune-associated genes, namely, scavenger receptor (SR) proteins, which are collinear to those in the closely related Cyclina sinensis genome. This finding suggested a high degree of conservation among immune-associated genes. Twenty-two (19%) SR proteins are tandemly duplicated in Sa. purpuratus genome, suggesting putative convergence evolution. Overall, Sa. purpuratus genome provides a new resource for the discovery of economically important traits and immune-response genes.
