1 · What the graph read from it

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.

2 · The registry

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

The fetomaternal interface (FMi), comprising fetal chorionic trophoblast cells (CTCs) and maternal decidual stromal cells (DECs), plays a critical role in providing immune tolerance during pregnancy. Intrauterine inflammation is major trigger of adverse outcomes such as preterm birth, yet the cell-specific inflammatory responses at the FMi -; poorly defined. We investigated differential inflammatory responses of fetal and maternal cell populations at the FMi upon exposure to endotoxin (lipopolysaccharide [LPS]). Primary CTCs and DECs were isolated from human term fetal membrane tissues. Cells were treated with LPS (100 ng/mL, 48 h. Transcriptomic profiling, multiplex immunoassays and western blotting was performed. Regulatory network analysis identified upstream drivers of cell-specific responses. LPS induced a pronounced inflammatory response in DECs, marked by high expression of proinflammatory chemokines, and prostaglandin enzymes associated with adverse pregnancy outcomes. In contrast, CTCs exhibited attenuated response, characterized by selective induction of stress-associated genes with minimal activation of inflammatory pathways. Network analysis revealed distinct cell type-specific regulatory hubs, including STAT1 and IRF7 in DECs and RELA and MYD88 in CTCs. DECs also activated anti-inflammatory signaling and pyroptosis-related pathways, which were largely absent in CTCs, indicating compartmentalized immune regulation Our findings demonstrate fundamental heterogeneity in inflammatory responses at the FMi, with maternal cells exhibiting greater sensitivity to endotoxin-induced activation compared with fetal CTCs. These differential responses may protect the fetus from excessive inflammation. Understanding cell-specific responses provides a foundation for understanding tolerance and mediators of intolerance at the FMi and identifying potential targets for therapeutic strategies in inflammation-associated pregnancy complications.
