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
objectiveVenison (deer meat) is increasingly favored by consumers for its safety, nutrition, flavor, and natural qualities. However, venison cuts in different regions of the carcass have different meat quality due to their distinct physiological function. To investigate the molecular basis of these variations, RNA-seq was used to compare gene expression pattern across different cuts of venison.
methodsIn this study, we performed a transcriptomic analysis based on RNA-seq data of 72 cuts from 6 different body parts of sika deer (Cervus nippon, n = 12), with the aim of understanding the genetic factors affecting the differences in venison quality, providing important references for further deer breeding.
resultsWe identified 139,111 expressed genes, including 79 region-specific genes enriched in pathways crucial for meat texture, tenderness, and nutrition. Differential gene expression analysis revealed significant variations among venison cuts, especially between the longissimus dorsi and trapezius cuts, highlighting roles in metal ion transport, organic acid biosynthesis, and glycolysis/gluconeogenesis. Additionally, fatty acid metabolism genes showed stable expression, while muscle fiber structure genes varied, affecting tenderness and juiciness.
conclusionOur findings provide insights into the genetic factors influencing venison quality, offering a foundation for future breeding strategies to enhance meat quality.
