The complete mitochondrial genome of an endemic cichlid Etroplus canarensis from Western Ghats, India (Perciformes: Cichlidae) and molecular phylogenetic analysis.
Article in Molecular biology reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundThe Indian endemic cichlid Etroplus canarensis (Canara pearl spot) is an endangered fish and is one among the three Indian cichlids (Etroplinae) that had a restricted distribution in the South Canara region of Karnataka, India. Despite considerable investigations, the phylogeny of Indian Cichlids and its biogeographical origin is still ambiguous and remains a question under discussion which is scrutinized based on whole mitogenomes in the present study. METHODS AND
resultsWe report the 16,339 bp complete mitochondrial genome of E. canarensis for the first time using the next-generation sequencing methods. Comparison of gene arrangement and genome characterization was found to commensurate with the previous reports on two Indian cichlid fishes, E. suratensis and E. maculatus. ND6 has been identified as a gene with the highest evolutionary rate and COI and COII is the most conserved gene based on p-genetic distance calculation. Substitution rate (ka/ks) was found to be very low indicating a reduced rate of evolution among subfamily Etroplinae accounting for its subsided species divergence of Indian cichlids. Phylogenetic analysis of Indian cichlids based on a combined dataset of 12 protein-coding genes representing cichlids generated high posterior probability values pillaring paraphyletic nature of Indian Malagasy lineage and monophyletic Indian genus Etroplus.
conclusionThe mitogenome sequence of E. canarensis may provide fundamental molecular data useful for further researches on genetic diversity, endemicity and the conservation of this endangered freshwater fish.
