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
The prognostic value of ring finger protein 215 (RNF215) in colorectal cancer (CRC) is unclear. Herein, the present study aimed to investigate the precise value of RNF215 based on CRC datasets from The Cancer Genome Atlas (TCGA) and clinical cases. CRC patient data was collected from TCGA and clinical samples from the Department of Pathology, Shanghai Fifth People's Hospital, Fudan University (Shanghai, China). Logistic regression analysis was used to investigate the correlations between RNF215 and clinicopathological characteristics. The predictive value of RNF215 for the clinical outcome of CRC was determined using Kaplan-Meier curves and Cox regression. Gene set enrichment analysis (GSEA), single-sample GSEA (ssGSEA), and angiogenesis analysis were also conducted to investigate the biological role of RNF215. Immunohistochemistry was conducted to validate the results. The results of the present study confirmed that RNF215 protein expression was significantly associated with age, lymphatic invasion, and overall survival (OS). Univariate analysis showed that upregulation of RNF215 in CRC was significantly associated with age and lymphatic invasion. Kaplan-Meier survival analysis revealed that high RNF215 expression predicted poorer OS and disease-specific survival. A total of nine experimentally detected RNF215-binding proteins were identified with the STRING tool and Cytoscape software. GSEA suggested that RNF215 was associated with several important pathways involved in tumor occurrence, including the Kyoto Encyclopedia of Genes and Genomes MAPK signaling pathway and the WikiPathway RAS signaling pathway. ssGSEA confirmed that RNF215 was significantly expressed in natural killer cells, CD8 T cells and T helper cells. Angiogenesis analysis revealed that numerous angiogenesis-related genes had the same expression trend as RNF215 in CRC. The immunostaining results indicated that RNF215 expression was significantly higher in CRC tissues than in corresponding normal tissues. In conclusion, increased RNF215 expression may be a potential molecular marker predictive of poor survival and a treatment target in CRC. In addition, RNF215 may participate in the formation of CRC through a variety of signaling pathways.
