The P450 genes of the cat flea,
Article in Current research in insect science, 2022. 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
The genome of the cat flea, an ectoparasite of major veterinary importance and the first representative of the Siphonaptera, is highly unusual among arthropod genomes in showing a variable size and a very large number of gene duplications (Driscoll et al., 2020). The cat flea is the target of several classes of insecticides, justifying the description of its CYPome, the complement of P450s that are an important family of detoxification enzymes. 103 P450 genes were annotated on the nine chromosomes, with an additional 12 genes on small, extrachromosomal scaffolds. Only 34 genes were found as single sequences, with 47 duplicated two to four-fold. This included duplication of genes that are mostly single copy P450 genes in other arthropods. Large clusters of mitochondrial clan P450s were observed, resulting in a CYP12 bloom within this clan to 34 genes, a number of mitochondrial P450s not seen in other animals so far. The variable geometry of the cat flea CYPome poses a challenge to the study of P450 function in this species, and raises the question of the underlying causes of single copy control versus multicopy licence of P450 genes.
