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

Birth weight is a key economic trait in pig breeding, affecting pre-weaning survival, growth performance, and overall production efficiency. However, the genetic factors underlying birth weight remain incompletely understood. This study aimed to identify genetic variants associated with birth weight in pigs through a genome-wide association study (GWAS) using 50K SNP genotyping data from 1125 Landrace pigs. Seven significant SNPs linked to birth weight were identified, along with 13 potential candidate genes. To validate these findings, the study population was expanded to include 998 Yorkshire pigs, totaling 2123 individuals. Validation identified two novel SNPs on chromosomes 1 and 16, as well as the previously unreported gene
