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

Rainbow trout (Onchorhynchus mykiss) is one of the most important freshwater aquaculture fish in Iran. It is necessary to develop available molecular marker such as SNPs, which represent a useful tool in detecting adaptive signals in populations and also parentage assignment for O. mykiss. Genetic architecture of broodstock populations is important for breeding programs, as it enables decisions on broodstock screening and genomic selection. In this study, 52 novel single nucleotide polymorphism (SNP) markers for O. mykiss were discovered and validated based on transcriptome sequencing, by means of paired-end sequencing in an Illumina HiSeq 2500 platform. The SNPs were identified through liver transcriptome sequencing from fifteen samples. The observed and expected heterozygosities ranged from 0.177 to 1.000 and 0.239 to 0.638, respectively. The minimum allele frequency (MAF) ranged from 0.166 to 0.489. Among these SNP loci, twenty-two loci showed significant departures from the Hardy-Weinberg equilibrium after Bonferroni correction (p < 0.05) and significant linkage disequilibrium was found. The SNP markers identified in this research could be useful for novel studies, such as those related to associations between high-resolution molecular markers and quantitative traits studies. Moreover, these SNP markers would be used in genetic studies helping economic performance improvement and management of this species.
