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
backgroundThe purpose of this study was to introduce a unified single-platform workflow for fabricating a patient-specific, multi-material 3D printing model of an impacted mesiodens. The workflow integrates CBCT and intraoral scans within a single planning platform and incorporates a fully detachable modular design and an elastic gingival layer to enable realistic soft-tissue simulation and stepwise surgical rehearsal. CASE PRESENTATION: Cone-beam computed tomography (CBCT) and intraoral scans were obtained for a patient with a fully impacted mesiodens. Using a single planning platform, anatomic structures (including teeth, bone, and gingiva) were segmented, and modular, engaging components were designed using computer-aided design functions. A multi-material model with detachable layers was fabricated using 3D printing to permit stepwise rehearsal: flap design, osteotomy, and tooth removal. The model accurately reflected patient-specific anatomy, and the elastic gingival component enabled realistic soft-tissue manipulation. This enhanced the fidelity of preoperative planning and provided improved educational value by visualizing anatomical relationships in stages.
conclusionsThis study demonstrates the feasibility of a unified single-platform workflow integrating CBCT and intraoral scans to produce patient-specific, detachable, multi-material 3D models. By combining modular design with soft-tissue simulation, the method supports clear, stepwise visualization of the mesiodens site.
