Transcriptional Profiling of Primordial Germ Cells During Chicken Embryonic Development.
Article in Veterinary sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Primordial germ cells (PGCs) are the earliest precursors of gametes and essential cellular materials for poultry germplasm conservation and genetic modification. In this study, PGCs isolated from 2.5-day male and female Silkie chicken embryos were defined as circulating PGCs (cPGC_M and cPGC_F), whereas PGCs isolated from 8.5-day male and female embryos were defined as gonad-derived PGCs (gPGC_M and gPGC_F). RNA sequencing with three biological replicates per group was performed to characterize developmental-stage- and sex-associated transcriptional programs. Comparative transcriptomic analyses identified stage-associated differences in pathways related to cell-matrix interaction, focal adhesion, PI3K-Akt signaling, and stem cell pluripotency, with more differentially expressed genes detected in the female than in the male stage comparison. Sex-biased expression was detectable at the circulating stage, mainly reflecting W- and Z-linked expression differences, and the number of sex-biased genes was greater after gonadal colonization, primarily because more autosomal differentially expressed genes were detected.
