Comparative analysis of lip morphology in Brazilian caucasian individuals between 20 and 50 years old using stereophotogrammetry.
Observational study in Oral and maxillofacial surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeThis observational, cross-sectional study evaluated healthy Caucasian Brazilian individuals' normal lip dimensions according to sex and age (20-50 years) using stereophotogrammetry.
methodsA total of 130 individuals divided into four groups according to sex and age were analyzed using stereophotogrammetry. Ten linear lip, five angular lip, and three lip surface measurements (upper, lower, and total lip vermilion) were obtained. Comparisons were performed using two-way ANOVA.
resultsMouth width, philtrum width, and lower lip cutaneous height were significantly greater in men than women. The upper lip height, upper lip cutaneous height, and average lower vermilion lip angle were significantly larger in men than women and increased with age (group), with medium or large effect sizes. A sex × group interaction was present for total vermilion height, upper vermilion height, total lip height, lower lip height, average upper vermilion lip angle, average Cupid's bow angle, mentolabial angle, and upper and total vermilion lip areas. When factors interact (sex/group), one affects the outcome of the other.
conclusionsRelevant linear lip measures were greater in men than women and increased with age in a mixed population from 20 to 50 years old. Thus, the lip and mouth are severly impacted by aging.
