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 aim of this study was to investigate the differences in the gene expression profiles of radiation-sensitive (RS) and radiation-resistant (RR) sinonasal squamous cell carcinoma (SNSCC) and to identify prognostic markers for the radiation reaction of SNSCC. We first examined the differentially expressed genes (DEGs) in RS and RR SNSCC tissues by analyzing clinical samples with GeneChip Human Transcriptome Array 2.0 (HTA 2.0).To understand the functional significance of the molecular changes, we examined the DEGs with Gene Ontology (GO) and pathway analyses to identify the core genes. The expression of several core genes (CCND2, COL5A2, GADD45B, and THBS2) was confirmed with reverse transcription quantitative PCR (RT-qPCR) in a larger series of tissues. We identified 208 DEGs, of which 76 were upregulated and 132 downregulated in the RS tissues relative to the RR tissues. The DEGs were mainly involved in the regulation of cell proliferation, the NF-kappaB signaling pathway, the cell adhesion molecule signaling pathway, and the extracellular matrix-receptor interaction signaling pathway. RT-qPCR confirmed that the CCND2, COL5A2, GADD45B, and THBS2 genes were significantly differentially expressed in the RS and RR tissues, consistent with the GeneChip data. These results extend our understanding of the molecular mechanisms underlying the sensitivity of SNSCC to radiation. The DEGs are involved in the differential response to radiation therapy and the dysregulated core genes identified in this study can be used to predict radiation sensitivity in SNSCC.
