Alveolar branches of canalis sinuosus: a radiographic and morphometric assessment by cone beam computed tomography.
Article in BMC medical imaging, 2025. 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
backgroundEvaluation of the alveolar branches of the canalis sinuosus (ABCS) to analyze its features and determine whether it is a variation or anatomical structure.
methodsABCS was assessed retrospectively from the ramification site to the end of its trajectory using cone-beam computed tomography, considering the sex, age, and voxel size of the images. Descriptive analysis, Chi-square test, Fisher-Freeman-Halton's exact test, Mann-Whitney U test, and Pearson and Spearman rank correlations were used for statistical analysis.
resultsA total of 167 ABCS were identified in 82 (72.6%) of 113 individuals. An ABCS wider than 1 mm was observed in 32.7% of individuals. The presence or number of ABCS was independent of age and sex (P˃0.05). The ramification site of the ABCS from the main canal was 96.4% below the nasal cavity floor, mostly at the level of the central incisors (46.1%). A significant difference was defined between the origin and end of the ABCS trajectory (P < 0.000). The end of the ABCS trajectory as vestibulo-palatal was 44.9% buccal and 35.9% palatal surface of the bone. The voxel sizes of the images were negatively correlated with the number of ABCS per individual (P = 0.002).
conclusionsABCS is more likely to be an anatomical structure than an anatomical variation, but many are less than 1 mm in diameter.
