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 leptin gene was studied as a marker for productive traits in Balkhi sheep. A total of 60 blood samples were collected from Balkhi sheep, and body measurements and weights were recorded. In the CDS (coding sequence) region of the Leptin gene, a 471 bp fragment was amplified by PCR with a pair of (forward and reverse) specific primers. Two novel SNPs were detected at positions (g.348 G > T) and (g.394 G > A). The highest genotypic frequency at position g.348 G > T was found for genotype GG (71.67%), followed by GT (20.00%), and TT exhibited the lowest frequency (8.33%). A similar pattern was observed for SNP2 at g.394 G > A, with the same genotypic frequencies: GG (75%), GA (18.33%), and AA (6.67%). In SNP1, the frequency of the G allele was highest in the population, at 81.67%, and the T allele was 18.33%. Similarly, in SNP2, the G allele was 84.17%, and the A allele was 15.83%. Both SNPs were significantly associated with some economically important body measurement traits. The results of this study can be concluded that, among the three genotypes of SNP1 (g. 348G > T) and SNP2 (g. 394G > A), the TT and AA genotypes could be used for the traits of economic importance like body length, fat-tail thickness, fat-tail length, and withers height in Balkhi sheep through marker-assisted selection for future breeding programs.
