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
The limited bone regeneration and suboptimal immune responses constitute the major challenges in repairing critical-sized bone defects. As an emerging therapeutic modality, mesenchymal stem cell-derived exosomes (MSC-Exos) exhibit promising application prospects in bone regeneration. In this study, the bone-functionalized MSC-Exos are loaded into GelMA hydrogel scaffolds modified with the bone immunomodulator Zeolitic Imidazolate Framework-8 (ZIF-8) for the repair of critical-sized bone defects. The prepared MSC-Exos/ZIF-8@GelMA composite hydrogel demonstrates excellent biocompatibility and favors the adhesion and proliferation of bone marrow mesenchymal stem cells (BMSCs). The sustained release of exosomes and zinc ions endows the composite hydrogel with synergistically enhanced bone regeneration, angiogenesis, and immunomodulation. Specifically, the microRNA-23a-3p within internalized MSC-Exos activates the AKT signaling pathway in BMSCs by targeting the PTEN node and up-regulates the expression of osteogenesis-related markers. Meanwhile, it is demonstrated for the first time that ZIF-8 inhibits the activation of the non-classical NF-κB pathway in RAW264.7 cells under simulated inflammatory conditions, thereby downregulating pro-inflammatory cytokine expression and inducing M2-type polarization. The rat cranial bone defect model demonstrates that the composite hydrogel significantly enhances new bone formation and angiogenesis
