Promegestone Prevents Lipopolysaccharide-Induced Cervical Remodeling in Pregnant Mice.
Article in Cells, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
In most mammals, a withdrawal of the pro-gestational hormone progesterone (P4) is necessary for labor onset. In murine cervix, P4 withdrawal is mediated by enzymes steroid 5-alpha-reductase type 1 (SRD5A1) and 20-alpha-hydroxysteroid-dehydrogenase (20α-HSD). Previously, we have shown that inflammatory stimuli induce 20α-HSD levels in uterine muscle (myometrium). Here, we hypothesized that (1) infectious inflammation alters the levels of both P4-metabolizing enzymes in mouse cervix, which consequently ceases P4-mediated inhibition of cervical remodeling, thereby inducing preterm labor (PTL); (2) a progestin, selective progesterone receptor modulator promegestone (aka R5020), non-metabolizable by 20α-HSD, can block lipopolysaccharide (LPS)-induced PTL in mice by maintaining P4 signaling and preventing cervical remodeling. Using RT-PCR and IHC/IF methods, we evaluated the effect of inflammation on the expression of both enzymes in mouse cervix and determined if R5020 can prevent cervical remodeling and PTL in mice. We found significant induction of SRD5A1 and 20α-HSD proteins (
