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/purpose: Regenerative endodontic procedures aim to biologically restore the dentin-pulp complex. Exosomes derived from dental pulp stem cells (D-Exo) have emerged as promising acellular therapeutic agents due to their ability to modulate the regenerative microenvironment. This study evaluated the regenerative potential of D-Exo-loaded hydroxyapatite/gelatin (HAp/Gel) scaffolds in dentin-pulp complex regeneration. Materials and methods: A biomimetic HAp/Gel scaffold was fabricated and characterized for morphology, swelling behavior, degradation, and cytocompatibility. D-Exo were isolated from dental pulp stem cells (DPSCs) and analyzed using transmission electron microscopy (TEM), nanoparticle tracking analysis, and western blotting. Their effects on DPSC proliferation were examined Results: The HAp/Gel scaffold exhibited an interconnected porous architecture, controlled degradation, and excellent cytocompatibility. Isolated D-Exo displayed typical vesicular morphology (approximately 117 nm) and expressed CD9, CD63, and CD81. D-Exo enhanced DPSC proliferation in a dose-dependent manner. μ-CT analysis revealed early mineralized tissue formation at 2 weeks and dentin bridge formation at 4 weeks, with more extensive mineralized deposition in the D-Exo-loaded HAp/Gel scaffold group. Conclusion: The D-Exo-loaded HAp/Gel scaffold demonstrated favorable biocompatibility and enhanced dentin-pulp complex regeneration
