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

Introduction: Knowledge of the internal anatomy of mandibular third molars is essential for successful endodontic treatment, yet their complex morphology often complicates management. This study evaluated the root canal morphology of mandibular third molars using cone-beam computed tomography (CBCT) according to Vertucci's classification. Materials and Methods: A total of 653 CBCT scans were screened, and 274 mandibular third molars meeting the inclusion criteria were analyzed. Root canal configurations were classified according to Vertucci, with atypical cases recorded as "type 0" for statistical purposes. Data were analyzed with Fisher's exact test (α=0.05). Results: Vertucci type I was the most prevalent configuration (62.8%), followed by type V (17.4%). Sex and dental arch side significantly influenced the distribution of configurations ( Conclusion: Mandibular third molars exhibit considerable anatomical variation, with types I and V being most frequent. Patient sex and arch side significantly affect root canal morphology, underscoring the importance of detailed preoperative assessment with CBCT for accurate endodontic planning.
