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

Indicine cattle display a broad range of coat colors, representing a relevant and breed-defining trait required for registration in breeder association. Among the genes involved in pigmentation, MC1R stands out for modulating the synthesis of melanin-related proteins and remains poorly explored in indicine cattle breeds. Therefore, we aimed to perform fine mapping of the MC1R gene and to evaluate the association between its polymorphisms and coat color as well as skin pigmentation in seven zebu cattle breeds. A total of 295 individuals belonging to Gir, Nelore, Sindi, Indubrasil, Tabapuã, Guzerá, and Brahman cattle breeds were genotyped through PCR-sequencing, followed by estimates of genotypic and allelic frequencies, linkage disequilibrium, and association with phenotypes using the Kruskal-Wallis test. We identified nine polymorphisms: six non-synonymous SNPs, one coding indel, one synonymous SNP, and one 3' downstream SNP. We report, for the first time, the SNP c.274G>A (p.Val92Met), here designated E
