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

The maturation of oocytes is a critical step in mammalian reproduction, involving dynamic regulation of gene expression. Therefore, investigating how gene expression varies during different stages of oocyte maturation is highly important. This study employed single-cell RNA sequencing (scRNA-seq) to analyze bovine oocytes at the germinal vesicle (GV) and metaphase II (MII) stages. The results identified 1787 differentially expressed genes (DEGs) between the two stages, with 1556 genes upregulated and 231 downregulated in the GV stage. Further investigation using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses indicated that the upregulated genes are mainly involved in mitochondrial functions and energy metabolism, whereas the downregulated genes are primarily associated with signaling pathways. Validation through RT-qPCR confirmed that
