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

Egg-laying rate is mainly determined by ovarian function and regulated by the hypothalamic-pituitary-gonadal axis; however, the mechanism by which the ovary regulates the egg-laying rate is still poorly understood. The purpose of this study was to compare the differences in the transcriptomes of the ovary of Lingyun black-bone chickens with relatively high and low egg-laying rates and screen candidate genes related to the egg-laying rate. RNA-sequencing (RNA-Seq) was conducted to explore the chicken transcriptome from the ovarian tissue of six Lingyun black-bone chickens with high (group G, n = 3) and low (group D, n = 3) egg-laying rates. The results showed that 235 differentially expressed genes (DEGs) were identified between the chickens with high and low egg-laying rates; among them, 209 DEGs were up-regulated and 26 DEGs were down-regulated. Gene Ontology analysis showed that the up-regulated 209 DEGs were enriched in 50 GO terms and the down-regulated 26 DEGs were enriched in 40 GO terms. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed that up-regulated DEGs were significantly enriched in 25 pathways and down-regulated DEGs were significantly enriched in three pathways. Among the pathways, we found the longevity regulating pathway-multiple species pathway, Estrogen signalling pathway and PPAR signalling pathway may have an essential function in regulating the egg-laying rate. The results highlighted DEGs in the ovarian tissues of relatively high and low laying Lingyun black-bone chicken and identified essential candidate genes related to the egg-laying rate, thereby providing a theoretical basis for improving the egg-laying rate of Lingyun black-bone chicken.
