Single Nucleotide Polymorphisms of Growth Hormone and Insulin-Like Growth Factor-1 Genes and Their Association With Growth Traits of Goats: A Systematic Review.
Synthesis in Veterinary medicine and science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Insulin-like growth factor-1 (IGF-1) and growth hormone (GH) genes are vital for animal growth. This study aimed to review the single nucleotide polymorphisms (SNPs) of IGF-1 and GH genes and their associations with growth traits of goats. This study is in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Databases (Google Scholar, PubMed, ScienceDirect and Web of Science) were evaluated. Eight SNPs of the IGF-1 gene were found in the selected studies, whereas nine SNPs of GH gene were discovered. One article found two SNPs (1617 G>A and 5752 G>C) that were similar to the ones of two other articles, each for the GH gene, and these articles found that body weight (BW) was not associated with the SNPs. All the other articles discovered different SNPs from each other for both genes. Four of the articles found an association between GH genotypes and BW. One article discovered a relationship between GH genotypes and withers height and chest width (CW) and three articles found an association between GH genotypes and heart girth (HG). Four articles discovered an association between IGF-1 genotypes and BW and one article discovered it with CW. This study concluded that the IGF-1 gene might be used as a potential molecular marker for the genetic improvement of BW and CW in goat breeding, whereas the GH gene can be used for the genetic improvement of BW, withers height, HG, body length and CW in goat breeding.
