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
objectiveTo explore the biological relationship between the regulatory signal pathways involved in differentially expressed genes and recurrent spontaneous abortion (RSA) by analyzing the gene expression microarray data of unexplained RSA.
methodsThe gene expression profile data of chorionic villi from unexplained recurrent abortion with normal karyotype and selective induced abortion were compared. Differentially expressed genes were analyzed by the "Limma" package in R Studio, and Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were carried out with "Cluster Profiler" and "org.hs.eg.db" packages. Finally, hub genes were identified through constructing the protein-protein interaction (PPI) network from the differentially expressed gene dataset in the STRING database. And the hub genes were verified by RT-PCR. The expression of TH1 and TH2 cytokines representing IL-2, IL-10 and their receptors related to hub gene immune regulation were detected by enzyme-linked immunosorbent assay (ELISA) and western blot (WB), respectively.
resultsA total of 295 differentially expressed genes were identified in the dataset GSE22490, with a significance level of P < 0.05 and an absolute log-fold change > 1.0, which included 166 up-regulated genes and 129 down-regulated genes. Go and KEGG enrichment analysis of these differentially expressed genes (P < 0.05,FDR < 0.05) revealed significant involvement in the regulation of inflammatory and immune responses. The PPI analysis revealed that the hub genes FCGR3A, TLR2, BTK, CLEC7A and CD163 were centrally located in the network cluster which were composed of the proteins encoded by differentially expressed genes associated with RSA. The mRNA levels of FCGR3A, TLR2 and CLEC7A in the RSA group were significantly higher than those in the NC group (P < 0.05). The protein expression level of TLR2 was also significantly increased in the RSA group (P < 0.05). The level of IL-2 in the RSA group was significantly higher than that in the NC group (P < 0.05), while the protein expression level of its receptor was not different(P > 0.05). There was no significant difference in the expression levels of IL-10 and its receptor between the two groups (P > 0.05).
conclusionAbnormal immune response plays an important role in unexplained RSA. The imbalance in immune regulation may be one of the most important reasons behind this phenomenon. These findings provide a foundation for further research into the mechanisms underlying RSA.
