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
Background: Uterine sarcoma is a gynecological mesenchymal tumor with an elusive pathogenesis. The uterine leiomyosarcoma (LMS) is the most common subtype of uterine sarcoma. LMS is a highly aggressive tumor with a poor prognosis. The genomic landscape of LMS remains unclear. Rare cases of LMS are observed to arise from leiomyoma (LM). We conducted a study to explore the genomic relationship between LMS and LM using public microarray data from the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA). Using bioinformatics analysis tools, we would like to provide molecular insight into the pathogenesis of LMS and to discover novel predictive biomarkers for this disease. Methods: LMS and LM differentially expressed genes (DEGs) were screened by analyzing GEO datasets; GSE764, GSE68312 and GSE64763; and TCGA data. A protein-protein interaction (PPI) network was constructed, and hub genes were identified utilizing the CytoHubba plug-in from Cytoscape software. In addition, weighted gene co-expression network analysis (WGCNA) was performed to identify hub genes. We took the intersection of the hub genes generated from the PPI network and WGCNA. Subsequently, random forest (RF) and support vector machine (SVM) algorithms were used to screen for key genes as predictive biomarkers. Finally, we constructed a nomogram with these genes. Results: A total of 37 hub genes were selected using WGCNA. A total of 245 DEGs were identified; 63 DEGs were upregulated, and 182 DEGs were downregulated. Functional enrichment analysis revealed that these genes were mainly associated with the cell cycle, extracellular matrix receptor interactions and oocyte meiosis. The final hub genes were Conclusions:
