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
objectivesTongue squamous cell carcinoma (TSCC) is a common cancer in the oral and maxillofacial region, which seriously endangers people's life and health.Heterogeneous nuclear ribonucleoprotein A2/B1(hnRNP A2/B1) is an RNA-binding protein that regulates the expression of a variety of genes and participates in the occurrence and development of a variety of cancers. This study aims to investigate the role of hnRNP A2/B1 in TSCC progression.
methodsThe differential expression of hnRNP A2/B1 in oral squamous cell carcinoma (OSCC) and normal oral mucosa cells and tissues was analyzed based on the gene expression profiles of GSE146483 and GSE85195 in the Gene Expression Omnibus (GEO) database. The correlation between hnRNP A2/B1 expression and disease-free survival of TSCC patients was analyzed based on TSCC related chip of GSE4676. TSCC cancer and paracancerous tissue samples of 30 patients were collected in Hunan Cancer Hospital from July to December 2021. Real-time RT-PCR and Western blotting were used to verify the mRNA and protein expression of hnRNP A2/B1 in TSCC patients'samples, respectively. Human TSCC Tca-8113 cells were transfected with hnRNP A2/B1 empty vector (a sh-NC group), knockdown plasmid (a sh-hnRNP A2/B1 group), empty vector overexpression plasmid (an OE-NC group) and overexpression plasmid (an OE-hnRNP A2/B1 group), respectively. The knockdown or overexpression efficiency of hnRNP A2/B1 was detected by Western blotting. The proliferation activity of Tca-8113 cells was detected by cell counting kit-8 (CCK-8), and the apoptosis rate of Tca-8113 cells was detected by flow cytometry.
resultsBased on the analysis of OSCC-related chips of GSE146483 and GSE85195 in the GEO database, it was found that hnRNP A2/B1 was differentially expressed in the OSCC and normal oral mucosa cells and tissues (all
conclusionsHnRNP A2/B1 is a key factor regulating the proliferation and apoptosis of TSCC cells. Inhibition of hnRNP A2/B1 expression can reduce the proliferation activity of TSCC cells and promote the apoptosis of TSCC cells.
