Associations of Serum Inflammatory Biomarkers During Pregnancy With Placental Pathology and Placental Gene Expression at Delivery.
Trial report in American journal of reproductive immunology (New York, N.Y. : 1989), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
problemWe sought to investigate whether maternal inflammatory cytokines during pregnancy are associated with histologic inflammatory or vascular lesions in the placenta and/or correlated with gene expression patterns in the placenta. METHOD OF STUDY: We leveraged data from a large randomized controlled trial (RCT) at a single site. Maternal serum was collected in the second and third trimesters, and a composite inflammatory score was created using five measured biomarkers (CRP, IL-6, IL-1ra, IL-10, and TNF-α). Placentas were collected at delivery for histological analysis and four major patterns of placental injury were characterized. Fresh small chorionic villous biopsies were collected for placental genome-wide mRNA profiling. Transcripts showing >2-fold differential expression over the 4-SD range of circulating inflammatory biomarkers were reported, adjusting for potential confounders.
resultsThe primary analysis included 601 participants. A one standard deviation increase in the third-trimester inflammatory composite was associated with increased odds of chronic inflammation in the placenta (OR: 1.23, 95% CI 1.01, 1.51;). This was driven primarily by elevations in IL-10 (OR: 1.37; 99% CI: 1.06, 1.77). Higher maternal IL-10 in circulation was associated with bioinformatic indications of reduced pro-inflammatory gene regulation pathways in the placenta (AP1 decreased 25%, p = 0.003; NF-kB decreased 53%, p = 0.003) and indications of increased STAT family signaling pathways which mediate signaling through the IL-10 receptor (increased 73%, p = 0.002).
conclusionsOur results indicate that elevated maternal circulating IL-10 during pregnancy is associated with chronic inflammatory lesions in the placenta at delivery. Additionally, higher levels of circulating IL-10 are associated with upregulated STAT signaling pathways in placental tissues.
