The rat mammary gland undergoes dynamic transcriptomic and lipidomic modifications from pre-puberty to adulthood.

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
Mammary gland development is a complex process involving dynamic interaction between the epithelial and stromal components at different critical stages, particularly around puberty. While epithelial tissue changes are well-documented, stromal mechanisms are less understood. To address this gap, this study employed histology, lipidomic, and transcriptomic analyses to investigate molecular and cellular dynamics in the mammary gland during pre-puberty (Post Natal Day (PND21)), peri-puberty (PND46), and adulthood (PND90) in rats. The epithelial area was significantly smaller at PND21 than at PND46 and PND90, with a higher complexity at PND21 compared to PND46. Significant differences in adipocyte number and size were observed between PND21, PND46, and PND90. Transcriptomic analysis revealed that 1563 genes changed significantly between PND21 and PND46, with only 14 genes altered between PND46 and PND90. Enrichment analyses indicated dynamic regulation of pathways related to proliferation, differentiation, lipid metabolism, and immune responses. In lipidomic analysis, 29/43 and 7/43 fatty acids differed significantly between PND21 - PND46 and PND46 - PND90, respectively. These results suggest that mammary gland development involves complex interactions between metabolic demands, hormonal regulation, and immune responses.
