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
Aim: The aim of this study was to evaluate the effect of impact stress on a primary central incisor with and without a strip crown and mouthguard using finite element analysis (FEA). Methodology: Four three-dimensional (3D) FEA models of a normal primary central incisor and strip crown with and without a 2 mm ethylene vinyl acetate (EVA) mouthguard were obtained from a cone-beam computed tomography (CBCT) scan of a 3-year-old child. Boundary conditions were defined. Impact analysis was carried out in Ansys Inc. software. Results: Results were obtained through von Mises analysis. Such analyses involve the process of color mapping to determine the distribution of stress. Normal primary maxillary central incisors without mouthguards and primary central incisors with strip crowns reported higher stresses compared to models with mouthguards. Conclusion: A 2 mm custom-fitted EVA mouthguard was effective in mitigating impact stress in the dentition of 3-5-year-old children. Therefore, the use of mouthguards should be encouraged in clinical practice, even for small children. How to cite this article: Mridul M, Chaudhary K, Khanduri N,
