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
Ferroptosis is an iron-dependent nonapoptotic form of cell death that links iron, lipid, and glutathione levels to a variety of disease-related activities. However, the characteristics of ferroptosis in cervical carcinoma (CC) are poorly understood. We acquired raw data on CC cohorts from The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) database. Key genes were identified using differential gene expression analysis and intersected for further immune infiltration, transcription regulation, gene set variation analysis (GSVA), gene set enrichment analysis (GSEA), and drug sensitivity analysis. We also used immunohistochemical (IHC) staining to confirm the expression of important genes in cervical cancer tissue and their prognostic relevance. Finally, gene silencing and cell coculture experiments were used to verify the biological functional mechanism and its role in the tumor microenvironment (TME). Through bioinformatics analysis, we discovered that GCH1 and H1.2 are key ferroptosis-related molecules in cervical cancer. GCH1 and H1.2 could act as useful prognostic markers in cervical cancer, and in addition to their connection with the tumor microenvironment, the possible transcriptional regulatory network, hallmark pathways and chemotherapy sensitivity were also clarified. IHC of the tissue microarray (TMA) and immunofluorescence spatial distance evaluation revealed that GCH1 was more highly expressed in cervical cancer tissue than in paracarcinoma tissue. For patients with cervical cancer, higher GCH1 expression corresponded to a lower M2 cell proportion and a higher M1/M2 ratio as well as a greater GCH1-M2 distance. Silencing GCH1 in SiHa cells blocked the cell cycle, promoted apoptosis, and inhibited the migration and invasion abilities of the cells, possibly through the inhibition of the phosphorylated PI3K/AKT/mTOR pathway. Coculture of the cells with macrophages revealed that the silencing of GCH1 led to decreased expression of tumor necrosis factor (TNF), a biomarker of M1 macrophages. In this study, we performed a thorough investigation of ferroptosis-related genes and identified the functional complexity of GCH1 during tumorigenesis in cervical cancer.
