VISTA drives pancreatic tumor progression through modulation of the tumor-associated macrophage polarity.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest malignancies due to its highly immunosuppressive tumor microenvironment (TME), which limits effective therapeutic interventions. Here, we demonstrate that V-domain immunoglobulin suppressor of T cell activation (VISTA) plays a crucial role in orchestrating macrophage polarity within the PDAC TME. Using murine PDAC models, we show that VISTA deficiency markedly impairs tumor growth, leading to prolonged survival. Functionally, VISTA deficiency is linked to a shift in tumor-associated macrophages (TAMs) from an immunosuppressive phenotype marked by secreted phosphoprotein 1 (SPP1), to one enriched for C-X-C motif chemokine ligand 9 (CXCL9), indicative of a pro-inflammatory state. This shift is accompanied by enhanced recruitment of CXCR3⁺ CD8⁺ T cells with sustained cytotoxic potential, among which terminal exhaustion-like CD8
