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
backgroundProlificacy-associated genetic markers can be utilized to enhance litter size in the sheep breeding industry. Sheep reproduction is influenced by a multitude of genes, including bone morphogenetic protein 2 (BMP2). This study aimed to explore the potential relationship between variability in the BMP2 gene and reproductive performance in Awassi and Hamdani ewes. METHODS AND
resultsThe genomic DNA was extracted from 99 single-progeny ewes and 101 twin ewes. Polymerase chain reaction (PCR) was employed to produce an amplicon consisting of four sequence fragments: 277 bp, 251 bp, 331 bp, and 340 bp, from exons 1, 2, 3, and 4 of the BMP2 gene, respectively. Three genotypes were identified for amplicons in exon 4 with 340-bp lengths: CC, CA, and AA. Upon analyzing the sequence of the CA genotype 382 C > A, a novel mutation was discovered in this genotype. A robust association was identified between the single nucleotide polymorphisms (SNP) 382 C > A and reproductive performance through statistical analysis. An important distinction was discovered between ewes carrying SNP 382 C > A and those carrying CC in terms of litter sizes, twinning rates, lambing rates, and days to lambing. An analysis of logistic regression revealed a significant association between litter size and the 382 C > A SNP. There was a decrease in lamb production among ewes with the CC genotype compared to those with the CA and AA genotypes.
conclusionsThese results indicate that the SNP variant 382 C > A has a positive influence on the reproductive performance of Awassi and Hamdani sheep. Sheep carrying the 382 C > A SNP exhibit increased litter size and overall productivity compared to those without the SNP.
