Fiber-reinforced composite restorations in endodontically treated teeth under functional loading.
Article in Bioinformation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Endodontically treated teeth remain highly susceptible to fracture due to significant loss of structural integrity and optimal restorative material selection remains a clinical challenge. Therefore, it is of interest to evaluate fracture resistance, marginal adaptation and microleakage of fiber-reinforced composite (FRC) restorations compared with conventional composite and metal-ceramic crowns under simulated functional loading. Ninety extracted human premolars were randomly assigned to three groups and subjected to cyclic loading (200 N, 500,000 cycles) using a chewing simulator. FRC restorations demonstrated significantly higher fracture resistance (987.4 ± 62.3 N) compared to conventional composite (743.2 ± 58.1 N) and showed comparable marginal adaptation to metal- ceramic crowns (p<0.001). Fiber-reinforced composites may provide a biomechanically superior and clinically viable alternative for restoring endodontically treated teeth, particularly in high load-bearing posterior regions.
