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
Aims and background: Conventional mouthguards, due to their increased thickness, are uncomfortable for the players. To increase the acceptability of mouthguards among players, this led to the development of a mouthguard that is 4 mm thick anteriorly and 2 mm thick posteriorly.In order to recommend this modified mouthguard to players, we need to find out its stress distribution pattern. For this, finite element analysis can be done Materials and methods: Modified and conventional mouthguard models were created after obtaining a cone-beam computed tomography (CBCT) scan of a 14-year-old child. Standardized forces were applied to 4 points (nodes) of the maxillary jaw. Results: The modified mouthguard showed minimum stress distribution in the left premolar region (1.83 MPa), whereas maximum stress distribution was observed in the maxillary left lateral incisor region (24.04 MPa).The conventional and modified mouthguards showed a displacement of 0.00624 mm and 0.000441 mm in the left premolar region, respectively. Conclusion: The modified mouthguard not only showed lower stress distribution but also exhibited minimum displacement compared to the conventional mouthguard when exposed to a standardized force of 614 N. Clinical significance: By reducing the thickness of the mouthguard, we can increase the acceptability of mouthguards among skating athletes. How to cite this article: Sawant SV, Kalaskar R.
