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
Resin composite veneers are widely used for esthetic rehabilitation of anterior teeth, offering a minimally invasive approach to restore tooth form and harmony. In indirect techniques, a digital diagnostic wax-up can define the final morphology; however, its accurate transfer to the clinical setting remains challenging and operator-dependent, potentially compromising restoration adaptation and introducing variability at the adhesive interface. This study describes a novel 3D-printed dual matrix system designed to improve the accuracy and reproducibility of the digital wax-up transfer. In the presented case, a 19-year-old patient with anterior diastemas and enamel defects was treated using a fully digital workflow. A diagnostic wax-up was used to fabricate a 3D-printed dual-matrix system with interlocking palatal and vestibular components, enabling guided positioning and controlled seating during the fabrication of the indirect resin composite veneers. The restorations were initially light-cured intraorally for stabilization, then removed and post-cured extraorally, followed by adhesive luting under rubber dam isolation. The proposed system enables a controlled and reproducible transfer of the digital diagnostic wax-up, facilitating the fabrication of indirect resin composite veneers. By improving restoration positioning and seating, it may enhance control of the adhesive interface and the predictability of bonding procedures for indirect resin composite veneers.
