Metabolic Reprogramming in Recurrent Spontaneous Abortion: Key Biomarkers Identification and Diagnostic Model Development.
Article in IET systems biology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Recurrent spontaneous abortion (RSA) involves complex and often unexplained pathogenesis. This study investigated metabolic reprogramming in RSA to identify diagnostic biomarkers. We integrated GEO datasets (GSE26787, GSE165004), identified metabolic reprogramming-related differentially expressed genes, and intersected them with WGCNA modules. Module genes were refined using logistic regression, SVM-RFE, and LASSO to construct a diagnostic model validated by ROC, nomogram, calibration, and decision curve analysis. The role of SREBF2 was explored by PCR, western blot, CCK-8, and transwell assays in vitro. Immune infiltration (ssGSEA, CIBERSORT) and single-cell RNA sequencing (GSE214607) explored immune-metabolic crosstalk. Results demonstrate critical involvement of metabolic reprogramming in RSA. Four model genes (SREBF2, PPARG, SQLE, UCP2) were upregulated in RSA and enriched in lipid/cholesterol pathways. Experimental validation confirmed SREBF2 upregulation in RSA decidua. Its overexpression in endometrial stromal cells impaired cell proliferation, decidualization, and trophoblast migration. Immune infiltration revealed correlations between model genes and specific immune subsets. Single-cell analysis identified altered immune cell proportions and cell-type-specific expression patterns, predominantly in macrophage subsets. This study indicates that lipid-centric metabolic remodelling may concurrently affect decidual function, trophoblast behaviour, and immune tolerance in RSA, offering diagnostic and therapeutic insights.
