2D:4D ratio as a predictor for malocclusion among Saudi children.
Article in Bioinformation, 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
2D:4D ratio is the ratio of the lengths of the index and ring fingers. It is a potential indicator of prenatal hormonal exposure, reflecting androgen sensitivity and it may influence skeletal and dental growth. Therefore, it is of interest to explore the correlation between the 2D:4D ratio and malocclusion types using Angle's classification of malocclusion in 410 male students aged 12-15 years from Alrass City, Saudi Arabia. Statistical analysis using Chi-Square tests revealed no considerable association between the 2D:4D ratio and malocclusion type (p=0.904). This data suggest that the ratio does not serve as a reliable predictor highlighting the complexity of factors influencing malocclusion and the need for further studies to better interpret hormonal, genetic and environmental contributions to craniofacial growth.
