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
The goat industry plays a crucial role in Malaysia's economy, with breeds such as Katjang and Boer being integral to the chevon supply. However, achieving self-sufficiency in goat meat production is still challenging due to the insufficient local carcass supply. To address this issue, a crossbreeding program has been initiated to improve reproductive performance in local breeds. In mammals, there are BMP15 and GDF9 genes, which are the components of the TGF-β superfamily that are key regulators of ovulation and litter size. This study aimed to improve reproductive performance in crossbred goats from Katjang and Boer populations in Sabah, Malaysia, by analyzing genetic variations in the BMP15 and GDF9 genes. A total of sixty female cross-Katjang goats, with recorded litter size and parities, were sampled. Five milliliters of blood was taken from the jugular vein using K2-EDTA tubes. Genetic analysis was performed using conventional PCR at the Biotechnology Research Institute, University Malaysia Sabah, followed by sequencing at Apical Scientific, Malaysia. Four novel polymorphic loci were identified within the GDF9 gene: G320C, A352G, G366T, and G375T. All of these loci resulted in missense mutations, causing a change in amino acid sequences. Notably, the A352G and G375T loci showed significant associations with litter size, with the AG genotype at position 352 and the GG genotype at position 375 emerging as potential markers for selective breeding. However, the polymorphic information content (PIC)values indicated low genetic diversity (< 0.25) at these loci. Interestingly, no polymorphisms were detected in the BMP15 gene, suggesting a monomorphic state (wild-type genotype) in the Cross-Katjang goat population. This finding indicates that BMP15 may not play a significant role in litter size variation in this crossbreed, shifting the focus towards GDF9 as a more relevant genetic marker for enhancing reproductive traits. This study provides important insights into the genetic factors influencing reproductive traits in crossbred goats, with potential applications in marker-assisted selection to improve reproductive and productivity performance.
