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
Calanthe arisanensis, a traditional medicinal orchid, contains Calanquinone A, a quinone-type compound with reported anticancer properties. Glioblastoma multiforme (GBM) is a highly aggressive brain tumor with limited treatment options and a poor prognosis. This study investigates the molecular mechanisms underlying the antiproliferative and antimigratory effects of Calanquinone A in GBM. Human GBM cell lines (U87MG) and patient-derived primary GBM cells (Pt#3) were treated with Calanquinone A (1-2.5 µM), and effects on cell viability, proliferation, and migration were assessed using CCK-8, trypan blue exclusion, colony formation, wound healing, transwell migration, and F-actin staining assays. Calanquinone A significantly reduced GBM cell viability and migration. Western blot analysis revealed that Calanquinone A inhibited STAT3 phosphorylation at Tyr705, leading to downregulation of its downstream targets c-Myc and MMP9. STAT3 overexpression reversed these effects, confirming the involvement of STAT3-dependent pathways. In a mouse xenograft model, Calanquinone A suppressed tumor formation in vivo. Molecular docking analysis further revealed a potential direct interaction between Calanquinone A and STAT3, supporting a direct mechanism of action. These findings demonstrate that Calanquinone A exerts potent antitumor effects in glioblastoma by targeting the STAT3/c-Myc and STAT3/MMP9 signaling axes, supporting its potential as a natural STAT3-targeting agent for GBM therapy.
