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
Metastasis and therapy resistance are main clinical challenges of pancreatic ductal adenocarcinoma (PDAC) still limiting patient`s prognosis. Both are dependent on tumor cell plasticity, which allows rapid adaptation of tumor cells to changing microenvironmental conditions. Epithelial-Mesenchymal-Transition (EMT), a process by which carcinoma cells acquire invasive abilities, is associated with a gain of cancer stem cell (CSC) properties. Different CSC phenotypes were described in PDAC, whereby high levels of the CSC marker Nestin was identified in CSC clones of mesenchymal Panc1 cells, while CSC clones of epithelial Panc89 cells were characterized by a high SOX2 expression. To investigate the functional impact of these CSC markers in PDAC cells with different EMT phenotypes, expression of either CSC marker was silenced in heterogenous (parental) and CSC PDAC populations to analyze their impact on essential malignancy associated properties.SiRNA-mediated knockdown (KD) of NES and/or SOX2 in Panc1 and Panc89 cell variants (parental and CSC population), respectively, was successfully achieved. Decreased NES expression in Panc1 cell variants and decreased SOX2 expression in Panc89 cell variants significantly inhibited self-renewing properties, however, only marginally impacted cell growth, EMT marker expression, migration and invasion properties as well as response to chemotherapy. Overall, our data indicate that Nestin and SOX2 are crucial mediators of self-renewal capabilities of mesenchymal and epithelial PDAC cell variants, respectively, but that further factors are required for the maintenance of other malignancy associated properties.
