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
backgroundPancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive human malignancies. Cell-cycle-related and expression-elevated protein in tumor (CREPT) plays an important role in the phosphorylation of RNA Pol II, and has been implicated in the development of several types of cancer. As yet, however, there have been no reports on its role in PDAC. Here, we aimed to explore the value of CREPT as a prognostic biomarker in PDAC.
methodsCREPT expression was assessed by immunohistochemistry (IHC) on a tissue microarray containing samples from 375 PDAC patients. Kaplan-Meier and Cox regression analyses were performed to explore the independent prognostic value of CREPT expression for the disease-free survival (DFS) and overall survival (OS) of PDAC patients. A Cell Counting Kit-8 (CCK8) assay was used to determine the growth rates and gemcitabine sensitivities of PDAC cells, while a Transwell assay was used to determine the migration and invasion abilities of PDAC cells. Subcutaneous xenografts were used to explore the effect of CREPT expression on tumor growth in vivo.
resultsWe found that CREPT is highly expressed in tumor tissues and may serve as an independent prognostic biomarker for DFS and OS of PDAC patients. In vitro assays revealed that CREPT expression promotes the proliferation, migration, invasion and gemcitabine resistance of PDAC cells, and in vivo assays showed that CREPT expression knockdown led to inhibition of PDAC tumor growth.
conclusionsWe conclude that high CREPT expression enhances the proliferation, migration, invasion and gemcitabine resistance of PDAC cells. In addition, we conclude that CREPT may serve as an independent prognostic biomarker and therapeutic target for PDAC patients.
