Molar Cervical Root Cross-Sectional Morphology and Diet in Extant Catarrhines.
Article in American journal of biological anthropology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesExternal tooth root morphology has demonstrated utility in understanding the mechanical function of teeth including patterns of loading during mastication and the overall mechanical challenge of foods consumed. Yet, there is still a paucity of information regarding how signals of diet, apart from these patterns, might be reflected in root form. This study examines whether a cross-section taken from the molar root cervix contains signals related to diet and masticatory function in extant catarrhine primates.
methodsMicro-CT scans of 11 genera of catarrhines were used to obtain 188 mandibular molars (M
resultsOLS regression of dentin area on mandibular length provided evidence of a strong relationship (r
conclusionsThe cervical root cross-section contains information regarding both the mechanical function of a tooth as well as conveying some aspects of dietary specialization, particularly for frugivorous catarrhines. This region provides a more nuanced understanding of dental adaptation along the folivore-frugivore continuum.
