TGF-β Inhibitor Potentiates Osimertinib-Induced Anti-Tumor Immunity in Egfr-Mutant Lung Cancer.

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
Immunotherapy for epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC) remains challenging. We previously found that EGFR-tyrosine kinase inhibitors induced antitumor immunity but also triggered immunosuppressive cytokines, including transforming growth factor-β (TGF-β), in Egfr-mutant lung cancer. Here, we investigate whether TGF-β inhibition potentiates osimertinib-induced antitumor immunity using a syngeneic mouse model of Egfr-mutated lung cancer, with cancer cells subcutaneously transplanted into wild-type C57BL/6J mice. We evaluated the antitumor effect of the combination therapy with osimertinib and either nintedanib (an indirect TGF-β inhibitor) or vactosertib (a specific TGF-β type I receptor kinase inhibitor). Changes in the tumor microenvironment during treatment were assessed using immunohistochemical staining, western blot analysis, and flow cytometry. We found that TGF-β expression was upregulated in the tumor treated with osimertinib. Nintedanib monotherapy showed no significant antitumor effect, whereas osimertinib combined with nintedanib significantly potentiates the antitumor effect compared with osimertinib monotherapy in vivo. Crucially, no additive effect of nintedanib on osimertinib monotherapy was observed in vitro. Combination therapy with osimertinib and nintedanib significantly increased effector T cells (CD8
