1 · What the graph read from it

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.

2 · The registry

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: To evaluate fracture strength (FS) and failure mode (FM) of additively manufactured endocrowns fabricated from two three-dimensional-printed resin composites with distinct inorganic filler contents, tested at two intracoronal preparation depths following thermomechanical aging. Materials and Methods: Twenty-eight endodontically treated human mandibular molars were restored using additively manufactured endocrowns according to material (Bio Crown or Voxelprint) and preparation depth (3 mm or 5 mm). After adhesive cementation and thermomechanical aging (300,000 cycles; 5°C-55°C), FS was measured under axial loading (0.5 mm/min), and FM were classified into four categories. Data were analyzed by two-way analysis of variance and Tukey's test (α = 0.05). Results: Restorative material significantly affected FS ( Conclusion: Resin composition influenced FS more than preparation depth. Increased depth did not improve load capacity but shifted failure toward more severe patterns.
