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
Pulmonary arterial hypertension (PAH) is a complex disease with multiple contributing factors. Epidemiological data showed that women are more susceptible to PAH, but they tend to have better right ventricular (RV) function and prognosis compared to men. The mechanisms behind these gender differences are not well understood. Using a variety of bioinformatic techniques, this study was aimed at investigating the major genes and putative pathways driving PAH in females. Consequently, microarray datasets GSE38267 and GSE131793 were obtained from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) in patients with PAH and healthy men and females were found via the use of volcano plots and Venn diagrams. Female-specific DEGs were selected for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses, with results visualized via R and Cytoscape software. The protein-protein interactions (PPIs) of female-specific DEGs were analyzed using the NetworkAnalyst online tool. Among identified DEGs, 98 DEGs were specific to males, 145 were shared among sexes, and 741 were unique to females. To focus on DEGs that are specific to female, male and shared DEGs were excluded. GO enrichment analysis revealed that these DEGs in females were mostly involved in cell-matrix adhesion, mucosal innate immune response, and hydrogen peroxide catabolism. Significant KEGG pathways included fluid shear stress, atherosclerosis, arrhythmogenic RV cardiomyopathy, and ECM-receptor interaction. Bioinformatic analysis of microarray datasets led to the identification of 10 female-specific hub genes, SLC4A1, THBS1, ITGB3, IL7R, CCR7, SNCA, CTNNB1, SELP, GZMK, and ITGA2B, from DEGs between control and PAH samples in females. These hub genes that are specific to females have the potential to be significant in the pathogenesis of PAH in females. These hub genes may be promising candidates for improving our knowledge of sex-related processes in PAH; nevertheless, experimental confirmation is necessary before considering them as biomarkers or therapeutic targets.
