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

Background: Pancreatic cancer (PC) is a highly aggressive pancreatic malignant tumor with poor prognosis due to its complex tumor microenvironment (TME) and metastatic potential. Fibroblasts play an important role in tumor progression and metastasis by remodeling the extracellular matrix (ECM) and influencing the immune response. This study explored migrasome-associated fibroblasts, especially TSPAN4 and ITGA5, as key regulators of pancreatic cancer metastasis, aiming to provide new ideas for therapeutic strategies targeting TME. Methods: We employed single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics to analyze pancreatic cancer tissues. Data from the GEO and TCGA databases were integrated and processed using batch correction techniques. Single-cell data were analyzed with Seurat and Monocle for dimensionality reduction and pseudotime trajectory analysis. Cell communication was assessed using CellCall and CellChat. Spatial transcriptomic analysis was conducted with RCTD and MISTy tools to investigate cell interactions within the TME. Additionally, gene enrichment, deconvolution, and prognostic analyses were performed, alongside experimental validation through siRNA transfection, qRT-PCR, and various functional assays to investigate the role of TSPAN4 in metastasis. Results: Our results underscore the critical role of TSPAN4 Conclusion: TSPAN4
