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: Restoring anterior teeth requiring angulation correction remains clinically challenging. Polyethylene fiber posts have been introduced, offering superior adaptability within the root canal and improved aesthetics. However, the effect of varying degrees of post angulation on the fracture resistance of restored teeth has not been thoroughly investigated. This study aimed to evaluate the fracture resistance of maxillary incisors restored using polyethylene fiber posts at varying angulations. Materials and methods: Thirty-two extracted incisors were selected according to the study criteria. Root canal treatment and gutta-percha removal were performed to prepare for polyethylene fiber posts. All study samples were subsequently divided into four groups of angulations: P1 (5°), P2 (10°), P3 (15°), and a control group (0°). Fracture resistance was tested, and the data were analyzed using one-way ANOVA followed by Post-Hoc comparison with the least significant difference (LSD) statistical tests. Results: A statistically significant difference in fracture resistance was observed among the groups, with group P1 demonstrating the highest fracture resistance (281.29 ± 84.97 N) and the control group exhibiting the lowest (164.75 ± 41.75 N). Conclusion: There was a difference in the fracture resistance of the maxillary incisors when using polyethylene fiber posts at angulation degrees of 5° and 0°, and angulation degrees of 5° and 15°. Therefore, anterior tooth restoration with angulation correction of 5°-10° can utilize polyethylene fiber posts.
