Frequency of A1 and A2 alleles of the β-casein gene in cattle in the Cajamarca region of Peru.
Article in Open veterinary journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Cow's milk β-casein has multiple genetic variants, the two most common of which are A1 and A2, which are encoded by the Aim: To determine the frequency of the A1 and A2 alleles of the β-casein gene in cattle. Methods: Blood samples were collected from 103 cattle (26 males and 77 females), 71 crossbred, 30 Simmental, 1 Jersey, and 1 Holstein. The selection prioritized females due to their economic value for milk production, reproductive potential, and capacity to replace cows of high genetic value, whereas males are intended for sale for meat production. Analysis of the A1 and A2 alleles of exon 7 of the Results: The heterozygous A1A2 genotype was the most frequent (50.5%, Conclusion: PCR-RFLP genotyping allowed the genotypic frequencies of β-casein to be determined, with 33.8% and 38.5% A2A2 in females and males, respectively.
