Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
Malignant bone tumor defects are difficult to treat because of the simultaneous need for tumor treatment and bone-repair promotion. This study presents a bioactive composite scaffold (T-rGO@Au) for personalized bone defect repair and bone tumor treatment. The T-rGO@Au scaffold has a porous structure, and its mechanical properties are close to those of human cancellous bone. The T-rGO@Au scaffold can induce upregulation of osteopontin (OPN), RUNX-2, and osteocalcin (OCN) gene expression. In vivo experiments showed that the bone volume/total volume (BV/TV) ratio with the T-rGO@Au scaffold was the highest. The new bone was tightly integrated with the implant, demonstrating effective osseointegration. The T-rGO@Au scaffold locally generated high temperatures and reactive oxygen species under near-infrared excitation, and AuNPs enhanced the photothermal performance of rGO through the "antenna effect." Furthermore, in vitro experiments showed that the tumor cell nuclei were destroyed, late-stage apoptotic cells increased, and cell morphology was severely damaged. Additionally, RNA-seq revealed that tumor cell destruction was mediated through signaling pathways, such as the MAPK pathway. In vivo antitumor experiments also demonstrated that the T-rGO@Au scaffold significantly inhibited the growth of tumor cells within 2 weeks. Thus, the T-rGO@Au scaffold provides a new treatment strategy for the development of implantable scaffolds for bone tumor defects.
