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
backgroundFibroblast growth factor receptor (FGFR) 4 is overexpressed in gastric cancer (GC) and is a potential therapeutic target for GC. Since the FGF/FGFR signaling is involved in tumor microenvironment inducing the formation of an immunosuppression, lenvatinib is expected to inhibit FGFR4 leading to reduced tumor PD-L1 levels and regulatory T cell (Treg) infiltration, improving pembrolizumab efficacy. This study explored the background of the molecular mechanisms underlying the therapeutic efficacy of lenvatinib plus pembrolizumab.
methodsExpression of FGFR4 and its specific ligand FGF19 was assessed by immunohistochemical staining and clinicopathological relevance was also examined. The effect of lenvatinib on FGF19-FGFR4 signaling was evaluated using cellular experiments. Lastly, the expression of FGFR4 on Treg cells was evaluated by immunostaining and flow cytometry. The Cancer Genome Atlas cBioPortal and Gene Expression Omnibus microarray databases were accessed to support these results.
resultsHigh FGFR4 expression was associated with histological type and venous invasion and predominantly detected in human epidermal growth factor receptor 2 and Epstein-Barr virus-positive GC. Bioinformatics data suggested that FGF19-FGFR4 signaling was activated in GC, and cellular experiments showed that lenvatinib reduced FGFR4 and PD-L1 expression in GC cells. Results of integrating various analyses suggested that FGFR4 did not seem to be enough expressed on Treg cells in GC.
conclusionsThe FGF19-FGFR4 signaling has a pivotal role in gastric tumorigenesis and may be involved in immunosuppression through PD-L1 modification. But, lenvatinib may not regulate immune editing by directly inhibiting FGFR4 on Treg cells.
