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
Postnatal mammary gland development involves the formation of a highly branched epithelial ductal tree, primarily through the elongation and branching morphogenesis of mammary epithelial ducts. Multiple factors are involved in this process, in which both estrogen and progesterone receptors (ER/PR) play a crucial role. In this study, we identified a role of DCAF8 in promoting mammary ductal elongation and branching through its impacts on ER/PR signaling. Homozygous Dcaf8 knockout mice exhibited significant delay in mammary ductal elongation during puberty, which was characterized by a reduction in mammary ductal elongation area and distance, and terminal end buds (TEBs); abnormal branching morphogenesis of mammary ducts was also observed in adult Dcaf8 null mice, which was characterized by a reduction of lateral branches and an increase of ductal bifurcation. To further elucidate the mechanism underlying DCAF8’s role in mouse mammary development, we performed transcriptomic sequencing and biochemical experiments. The results revealed that downstream key effectors of the PR signaling pathway were significantly downregulated, while the expression of ERβ, a potential inhibitor of ERα/PR signaling, was significantly elevated in the mammary gland of Dcaf8 null mice. Collectively, this study suggests that DCAF8 may play an important role in mammary development by promoting ductal elongation and branching morphogenesis, through ERβ-mediated inhibition of ERα/PR signaling pathway.
