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
DNA methylation of promoter regions is often associated with epigenetic silencing of gene expression, and DNA methyltransferase (DNMTs) has been used to suppress gene expression. In order to explore the synergistic roles of two methyltransferase members Dnmt3a and Dnmt1, we constructed expression plasmid that could express a recombinant DNMTs consisting of the C-terminal domains of both Dnmt3a and Dnmt1 fused to a zinc finger domain which binds to the PD-L1 promoter of human prostate cancer cells (DU145). Programmed death ligand 1 (PD-L1, B7-H1, CD-274) is a transmembrane protein widely expressed on antigen-presenting and other immune cells. The interaction of PD-L1 with its receptor PD-1 is considered an 'immune checkpoint' for possible cancer therapy. DU145 cells treated with the Dnmt3aC-1C plasmid showed significantly reduced expression of PD-L1 as compared to Dnmt3aC or Dnmt1C alone. Our results show that the fusion of Dnmt1 improves the methylation activity of Dnmt3a and enhances its biological functions. This combinatorial strategy can be used to better control PD-L1 expression to support cytotoxic T lymphocytes (CTL) response against tumors.
