Revisiting the taxonomy of the genus Rhodopirellula with the proposal for reclassification of the genus to Rhodopirellula sensu stricto, Aporhodopirellula gen. nov., Allorhodopirellula gen. nov. and Neorhodopirellula gen. nov.

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 current genus Rhodopirellula consists of marine bacteria which belong to the family Pirellulaceae of the phylum Planctomycetota. Members of the genus Rhodopirellula are aerobic, mesophiles and chemoheterotrophs. The here conducted analysis built on 16S rRNA gene sequence and multi-locus sequence analysis based phylogenomic trees suggested that the genus is subdivided into four clades. Existing Rhodopirellula species were studied extensively based on phenotypic, genomic and chemotaxonomic parameters. The heterogeneity was further confirmed by overall genome-related indices (OGRI) including digital DNA-DNA hybridization (dDDH), average nucleotide identity (ANI), average amino acid identity (AAI), and percentage of conserved proteins (POCP). AAI and POCP values between the clades of the genus Rhodopirellula were 62.2-69.6% and 49.5-62.5%, respectively. Comparative genomic approaches like pan-genome analysis and conserved signature indels (CSIs) also support the division of the clades. The genomic incoherence of the members of the genus is further supported by variations in phenotypic characteristics. Thus, with the here applied integrated comparative genomic and polyphasic approaches, we propose the reclassification of the genus Rhodopirellula to three new genera: Aporhodopirellula gen. nov., Allorhodopirellula gen. nov., and Neorhodopirellula gen. nov.
