A gene-expression signature defines a subtype of Stomach Adenocarcinomas with low levels of Claudins and a high ratio of NF-YA long/NF-YA short splicing variants.

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
backgroundClaudin-3, Claudin-4, and Claudin-7 are expressed on the surface of epithelial cells. Their absence in neoplastic cells of epithelial origin is an aggressiveness marker in different cancers. The NF-YA gene codes for the Nuclear-Transcription-Factor-Y-Subunit-A, which is overexpressed in various tumors. In tumors, the relative ratio of the two major NF-YA alternative splicing isoforms, NF-YA long and NF-YA short, is associated with a mesenchymal phenotype and a poor prognosis. Based on a high NF-YA long/NF-YA short ratio, we generated a 158-gene signature that is common to Claudin
methodsTo better classify STAD Claudin
resultsThe 158-gene signature resulted in the selection of a STAD subgroup with effective Claudin
conclusionsOur work supports the notion that three overlapping features-low expression of Claudin-3/4/7, high NF-YA long/NF-YA short ratio and a 158-gene signature-mark a specific subset of STAD characterized by mesenchymal features and poor prognosis.
