A microbiota-host axis mediates prostaglandin sensitivity: Lactobacillus crispatus as a biomarker and regulator of human labor induction.

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
Labor induction failure increases the risk of unplanned cesarean delivery and maternal-neonatal complications. However, the determinants of induction sensitivity remain poorly understood. In this prospective cohort of 85 term pregnant women undergoing labor induction with Propess® (prostaglandin E2), we combined full-length 16S rRNA sequencing of the vaginal microbiota, untargeted metabolomics of vaginal secretions, and transcriptomic analysis of cervical stromal cells exposed to Lactobacillus crispatus supernatant to identify predictive factors and underlying mechanisms. We found that women with a poor induction response exhibited higher vaginal microbiota α-diversity and a significant reduction in L. crispatus abundance. The relative abundance of L. crispatus predicted induction success with an area under the curve (AUC) of 0.80 (95% CI: 0.70-0.90). Metabolomic analysis revealed distinct vaginal metabolic alterations in induction-insensitive women. Importantly, in vitro experiments showed that L. crispatus supernatant directly modulates the transcriptome of cervical stromal cells, upregulating genes involved in uterine contraction, tissue remodeling, and immune regulation. Our results identify vaginal L. crispatus as a key biomarker for labor induction sensitivity and elucidate a potential mechanism by which it primes the cervix for prostaglandin response. These findings provide a novel microbiota-host interaction framework for personalizing induction strategies in precision obstetrics.
