Aesthetic preferences of the nasolabial angle: A three-dimensional (3D) study.
Article in JPRAS open, 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
Historically, the ideal nasolabial angle (NLA) ranges from 90° to 120°. This study was conducted to evaluate the current preferences of NLA of laypeople and clinicians based on 3D female textured and 3D male textured images. Three-dimensional software (Di3DView) was used to create a 3D facial image with a NLA of 70°. The colour images of one male and female adult were remapped onto the generated 3D image, resulting in a colour textured 3D male, and 3D female image, both with the same facial shape and a 70° NLA. This process was repeated for NLA's of 80°, 90°, 100°, and 110°. Based on a 7-point Likert scale, seventy-two laypeople and fifty clinicians were asked to evaluate the NLA of each rotating 3D image and give a facial attractiveness score. Clinicians and laypeople showed good intra-rater reliability (ICC 0.75 to 0.89). A 90° NLA was found to be most attractive for 3D male textured images (
