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
Liver metastasis is a major factor contributing to the poor prognosis of pancreatic ductal adenocarcinoma (PDAC). The formation of pre-metastatic niche (PMN) initiates the process of liver metastasis. Exosomes (Exos) act as key mediators of crosstalk between the tumor microenvironment (TME) and the PMN to activate hepatic stellate cells (HSCs) and remodel the stiff extracellular matrix (ECM). In this study, we isolated Exos derived from PDAC cells cultured under acidic conditions and demonstrated that these Exos significantly activate HSCs and promote the remodeling of the stiff ECM, thereby promoting the stemness, migration, and invasion of PDAC cells. High expression of exosomal miR-1246 was screened by miRNA-sequencing, and Wiskott-Aldrich syndrome protein Family Member 3 (WASF3) was identified as the target of miR-1246. Mechanistically, exosomal miR-1246 activates HSCs to remodel the ECM by targeting WASF3 and stimulating the phosphatidylinositol 3-kinase-serine/threonine protein kinase (PI3K/Akt) pathway. Notably, RNA-binding protein immunoprecipitation (RIP) and miRNA pull-down assays were performed to identify that Human Antigen R (HuR) contributes to the enrichment of miR-1246 into Exos. Collectively, exosomal miR-1246 activates HSCs and remodels the stiff ECM to promote liver metastasis, and it may serve as a potential diagnostic and prognostic marker for PDAC liver metastasis.
