1 · What the graph read from it

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.

2 · The registry

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 Indian black clam Villorita cyprinoides (Family: Cyrenidae), an extractive commercially exploited species with aquaculture importance contributing more than 70% of clam fishery in India, is endemic to the Indian peninsula. Currently, there is very sparse information, especially on the molecular data of Villorita. The present study aims to provide a comprehensive knowledge of mitogenome architecture and assess the phylogenetic status of Cyrenidae. This has resulted in reporting the first complete mitogenome of V. cyprinoides using next-generation sequencing technology. The A+T circular mitogenome was 15,880 bp long, exhibiting 13 protein-coding genes (PCGs) including ATP8 (absent in several bivalves), 22 transfer RNA, and two ribosomal RNA genes residing in the heavy strand in a clockwise orientation and a gene order akin to Corbicula fluminea. The molecular phylogeny inferred from a concatenated multi-gene sequence [14 mitochondrial (12 PCGs, rrnS and rrnL) and two nuclear genes (Histone H3, 18S rRNA)] from 47 representative species of superorder Imparidentia, clustered V. cyprinoides and Cyrenid clams to a single clade supporting the monophyly of Cyrenidae. The subsequent mitochondrial gene order analysis substantiates the close relationship of V. cyprinoides and C. fluminea, analogous to phylogenetic output. The multilocus tree topology calibrated with verified fossil data deciphered the origin and diversification of Cyrenid clams during late Triassic-early Jurassic. The data derived from this study shall contribute remarkably for further insights on cryptic species identification, molecular characterization of bivalve mitogenomes and mitochondrial evolutionary history of genus Villorita. Moreover, complete mitogenome can aid in potential marker development for assessing the genetic health of black clam populations.
