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
backgroundClear cell renal cell carcinoma (ccRCC) is an aggressive malignancy characterized by strong invasiveness and treatment resistance. Although SMARCD1 has been studied in several cancers, its function in ccRCC and its regulatory relationship with the key angiogenic factor VEGFA remain unexplored.
methodsClinical relevance of SMARCD1 was assessed through in vitro experiments and data analysis. Integrated in vivo and in vitro functional studies evaluated SMARCD1’s biological impact in ccRCC. SMARCD1-VEGFA epigenetic regulation was investigated via ChIP-qPCR, ATAC-qPCR, luciferase reporter assays, and HUVEC angiogenesis models. Bevacizumab-resistant cell lines and combination therapy models were established to validate SMARCD1’s role in drug resistance.
resultsSMARCD1 expression was significantly upregulated in ccRCC tissues and was strongly correlated with both disease progression and adverse clinical outcomes. Functionally, we have demonstrated that SMARCD1 promotes tumor proliferation, migration, and angiogenesis. Mechanistically, we have discovered that SMARCD1 binds directly to the VEGFA promoter, enhancing chromatin accessibility and modifying histone marks to activate transcriptional expression. The pro-tumor effects of SMARCD1 were found to be critically dependent on VEGFA. Furthermore, SMARCD1 knockdown sensitized bevacizumab-resistant ccRCC models to anti-angiogenic therapy.
conclusionThis study establishes that SMARCD1 promotes ccRCC progression and bevacizumab resistance by epigenetically remodeling the VEGFA promoter region. These findings provide a mechanistic foundation for novel precision therapies targeting the SMARCD1-VEGFA axis.
