Phylogenetic analysis, gene rearrangement and divergence time estimation of Patellogastropoda (Mollusca, Gastropoda) based on complete mitochondrial genomes.

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
backgroundPatellogastropoda, or true limpets, is a major taxonomic group within the Gastropoda, Mollusca. The complete mitochondrial genomes have been widely used to study the phylogenetic relationships of Patellogastropoda. To further enhance the understanding of the phylogenetic relationships among families within this subclass, we obtained the complete mitochondrial genome sequences of five species using third-generation sequencing technology: Limalepeta lima, Lepeta kuragiensis, Lottia versicolor, Lottia instabilis, and Lottia tenuisculpta. We examined mitochondrial genome structure, nucleotide composition and skew, as well as amino acid content and codon usage. Additionally, we assessed selective pressures on protein-coding genes in Lepetidae and Lottiidae species, constructed a phylogenetic tree for Patellogastropoda, analyzed gene arrangement, and estimated the divergence times within Patellogastropoda.
resultsThe mitochondrial genomes of these five species all encoded 38 genes. They exhibited a higher AT base content, and the protein-coding genes were under purifying selection. The Patellogastropoda was divided into two clades: Clade 1 included a part of the Lottioidea superfamily and the Patelloidea superfamily, whereas the Lottiidae family within the Lottioidea superfamily formed a separate clade (Clade 2). The mitochondrial genomes of the Patellogastropoda exhibited extensive gene rearrangements, particularly those in Lottiidae, which were the most complex. The Patellogastropoda lineage was estimated to have originated in the Paleozoic Permian era, with active differentiation occurring in the Mesozoic Cretaceous and the Cenozoic era.
conclusionsOur research results contribute to a better understanding of the phylogenetic relationships within the Patellogastropoda, and reveal the extensive gene rearrangements, providing further insights into the evolution and genetics of gastropods.
