Restriction site-associated DNA sequencing (RAD-seq) analysis in Pacific oyster Crassostrea gigas based on observation of individual sex changes.
Article in Scientific reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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 diverse modes of sexual reproduction in Bivalvia make it an excellent clade to understand the evolution of sex and sex determination. The cosmopolitan Pacific oyster Crassostrea gigas is an ideal model for bivalve sex determination studies because of its complicated sexuality, including dioecy, sex change and rare hermaphroditism. A major barrier to C. gigas sex determination study has been the lack of information on the type of sex determination. To identify its sex-determining system, sex observation by following the same individual in two consecutive years was conducted on 760 oysters from distinct populations. Stable sexuality and sex reversal in both directions were observed, which provides a case against the protandry of C. gigas. Restriction site-associated DNA sequencing (RAD-seq) based on 26 samples with unchanged and converted sexualities was carried out for identifying sex-linked marker. One SNP Cgsl-40 was proved to be sex-related, but sex-biased heterozygosity varied between populations for RAD-seq and validation, showing no evidence for sex chromosomes or single-locus models for C. gigas primary sex determination. Information obtained in our study provides novel insight into sex determination mechanism in C. gigas.
