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
Background: Temozolomide (TMZ) is a first-line chemotherapeutic agent for gliomas. However, its efficacy is limited by drug resistance. Platycodin D (PD) exhibits notable anti-glioma activity The objective of this study was to investigate the potential of PD to augment glioma sensitivity to TMZ and the underlying mechanisms. Methods: Cell viability and proliferation were assessed using CCK-8 and clonogenic assays, respectively, while flow cytometry was used to detect apoptosis. Cell migration and invasion were assessed using Transwell assays. Western blotting and immunohistochemistry analyses were performed to determine protein expression levels. A xenograft glioma model was established to investigate the in vivo effects of PD. Results: PD augmented glioma cell sensitivity to TMZ, as evidenced by heightened inhibition of cell growth, colony formation, migration, and invasion, accompanied by elevated apoptosis. Treatment with PD or a combination of PD and TMZ robustly suppressed the expression of active β-catenin and c-Myc, which was reversed by the β-catenin activator, SKL2001. In vivo experiments demonstrated that PD amplified the anti-glioma efficacy of TMZ, resulting in diminished Ki67 expression and substantially reduced expression of active β-catenin and c-Myc in the tumor tissue. Conclusion: PD augmented glioma cell sensitivity to TMZ by modulating Wnt/β-catenin pathway. Our findings demonstrate the potential of PD as an innovative therapeutic agent to enhance glioma treatment, especially in TMZ-resistant gliomas.
