1 · What the graph read from it

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.

2 · The registry

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

Interferon-stimulated gene 15 (ISG15) is a 15 kDa protein induced by type I interferons (IFN-α and IFN-β) and is a member of the ubiquitin-like superfamily of proteins. The ISG15 pathway is highly expressed in various malignancies, including pancreatic ductal adenocarcinoma (PDAC), suggesting a potential role of the ISG15 pathway (free ISG15 and ISG15 conjugates) in pancreatic carcinogenesis. However, very little is known about how the ISG15 pathway may contribute to pancreatic tumorigenesis. In the current study, we demonstrate that ISG15 pathway knockdown reverses the KRAS-associated phenotypes of PDAC cells such as increased proliferation and colony formation. Furthermore, clustered regularly interspaced short palindromic repeats (CRISPR)-mediated ISG15 knockdown decreased tumor programmed death ligand-1 (PDL-1) expression leading to increased number of CD8
