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

Background/purpose: Root canal morphology exhibits substantial anatomical variation influenced by ethnicity and sex, which may complicate endodontic treatment if unrecognized. This study aimed to comprehensively evaluate root and root canal configurations in a Taiwanese population using cone-beam computed tomography (CBCT) and to investigate sex-related differences in canal anatomy. Materials and methods: CBCT scans from 802 patients treated between 2022 and 2024 were retrospectively analyzed. A total of 18,578 teeth met the inclusion criteria. Root canal configurations were assessed for every root using Vertucci's classification, and C-shaped canals were further categorized based on morphology. Sex-related differences were analyzed using chisquare tests. Results: Complex canal configurations were frequently observed, particularly in molars. Distolingual roots were identified in 20.7% of mandibular first molars, and C-shaped canal configurations were present in 44.0% of mandibular second molars. Males exhibited a significantly higher prevalence of complex canals, including second mesiobuccal canals in maxillary molars and complex configurations in mandibular first premolars ( Conclusion: This study presents the first large-scale CBCT-based dataset of root and root canal morphology in an East Asian population, providing a comprehensive reference for Taiwanese individuals. Analysis of more than 1000 M in each group demonstrated substantial anatomical variability and significant sex-related differences, underscoring the importance of population-and sex-specific morphological datasets.
