Exploration of the auricle morphology of young adults from 10 countries.
Article in Scientific reports, 2026. 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
This study aimed to compare auricle morphology across individuals from 10 countries. A total of 1,351 auricle photographs from 676 student volunteers (367 males, 309 females) at Karabük University were analyzed. Participants originated from Türkiye, Chad, Morocco, Gabon, Iran, Kazakhstan, Uzbekistan, Senegal, Syria, and Jordan/Palestine. Morphological parameters included external auricle shape, helix form, antihelix, triangular fossa, antitragus, incisura intertragica, tragus, earlobe shape, earlobe-cheek attachment, and Darwin's tubercle. The participants were aged 16-30 years, with a mean age of 20.9 ± 3.3 years. Participants were aged 16-30 years (mean 20.9 ± 3.3). External auricle shape differed significantly by country (χ2 = 185.764, df = 54, p < 0.001), with round shapes predominant in Chad, triangular in Morocco and Kazakhstan, bagel in Gabon and Senegal, and oval in Türkiye, Uzbekistan, and Syria. Helix form also differed significantly (χ2 = 178.928, df = 63, p < 0.001). This study provides a standardized comparative framework of auricular morphology across multiple populations, offering a reference dataset that may support forensic identification, anthropological research, and clinical applications such as auricular reconstruction.
