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
backgroundDiffuse large B-cell lymphoma (DLBCL) is an aggressive malignancy where many patients relapse after standard therapy, necessitating novel approaches. Pyroptosis is an inflammatory cell death that can stimulate antitumor immunity. Histone deacetylases are frequently overexpressed in DLBCL and contribute to immune evasion. This study investigates whether combining the HDAC inhibitor chidamide with cisplatin and etoposide induces pyroptosis and enhances antitumor immune responses.
methodsWe evaluated chidamide combined with cisplatin and etoposide in diffuse large B-cell lymphoma cell lines and syngeneic mouse models. Cell death mechanisms were analyzed using immunoblotting and imaging. Tumor growth and immune cell infiltration were assessed in immunocompetent mice, with the role of adaptive immunity evaluated through CD8-positive T cell depletion. Statistical analyses included analysis of variance where appropriate.
resultsHere we show that chidamide synergistically potentiates cisplatin and etoposide efficacy by upregulating gasdermin E expression and promoting its caspase-3-dependent cleavage, thereby triggering pyroptosis. This combination remodels the tumor microenvironment, increasing infiltration of dendritic cells, natural killer cells, and CD8-positive T cells while reducing immunosuppressive macrophages. Depletion of CD8-positive T cells abolishes the therapeutic benefit, demonstrating their essential role.
conclusionsThe chidamide-cisplatin-etoposide combination triggers immunogenic pyroptosis via the caspase-3/gasdermin E axis and activates adaptive immunity. This regimen represents a promising therapeutic strategy for relapsed diffuse large B-cell lymphoma warranting clinical investigation.
