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

Senepol cattle carrying the slick hair gene are phenotypically characterized by short and sleek hair, which increases resistance to heat stress. To assess the impact of the slick hair genotype on growth, carcass, precocity, and feed efficiency traits, records from 5,176 purebred Senepol cattle undergoing commercial performance tests in Brazil were used. The animals were classified as homozygous for slick hair (SS) and heterozygous (Ss) and non-carriers (ss). The phenotypic results showed that heterozygous individuals were superior (P < 0.05) for yearling weight compared to others. When the results were expressed as expected progeny difference, Ss individuals were superior to SS individuals (P < 0.05) for yearling weight. While for ribeye area, SS individuals were superior (P < 0.05) compared to ss. In conclusion, genetic improvement programs for the Senepol breed should focus on strategies that promote the slick hair phenotype, to improve adaptability to tropical conditions without compromising progress in other traits.
