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
Gene delivery to esophageal tissue could provide novel treatments for diseases, such as cancer. The Sleeping Beauty (SB) transposon system, as a natural and non-viral tool, is efficient at transferring transgene into the human genome for human cell genetic engineering. The plasmid-based SB transposon can insert into chromosomes through an accurate recombinase-mediated mechanism, providing long-term expression of transgene integrated into the target cells. In this study, we aimed to investigate the activity of ED-L2 tissue-specific promoter that was engineered from the Epstein-Barr Virus (EBV) and combined with the hyperactive SB100X transposase to achieve the stable expression of T2-Onc3 transposon in esophageal squamous epithelial cells. Here we constructed an SB transposon-based plasmid system to obtain the stable expression of transposon upon introduction of a hyperactive SB transposase under the control of tissue-specific ED-L2 promoter via the lipid-based delivery method in the cultured esophageal squamous cell carcinoma cells. Among established human and mouse cell lines, the (ED-L2)-SB100X transposase was active only in human esophageal stratified squamous epithelial and differentiated keratinocytes derived from skin (KYSE-30 and HaCaT cell lines), where it revealed high promoter activity. Data offered that the 782 bp sequence of ED-L2 promoter has a key role in its activity in vitro. The (ED-L2)-SB100X transposase mediated stable integration of T2-Onc3 in KYSE-30 cells, thereby providing further evidence of the tissue specificity of ED-L2 promoter. The KYSE-30 cells modified with the SB system integrate on average 187 copies of the T2-Onc3 transposon in its genome. In aggregate, the (ED-L2)-SB100X transposase can be efficiently applied for the tissue-specific stable expression of a transgene in human KYSE-30 cells using SB transposon.
