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
introductionThis study aimed to assess whether sagittal maxillary-mandibular skeletal relationships influence perceived facial esthetics in patients with varying sagittal skeletal discrepancies.
methodsWe analyzed 3-dimensional facial models from cone-beam computed tomography scans of 40 patients (17 males and 23 females aged 14-48 years; ANB = 0°-10°), lacking skin color or hair, to isolate shape. A total of 100 laypeople rated these for esthetics and sexual dimorphism using visual analogue scales. Procrustes-based 3-dimensional geometric morphometrics quantified shape, and multivariate linear regression estimated vectors for visual analogue scales ratings. Linear regression tested correlations between shapes linked to the ANB angle and esthetics.
resultsPerceived attractiveness was unrelated to age, asymmetry, or deviation from the population average shape. Esthetics correlated with lower facial third shape (r
conclusionsSagittal maxillary-mandibular relationships, as measured by the ANB angle and sagittal skeletal discrepancy, modestly influence facial esthetics, with straighter profiles and prominent chins rated more attractive. These findings suggest a partial biological basis for esthetic preferences, though individual and cultural factors, including smile esthetics and dental symmetry, also play a role. The study informs orthodontic treatment planning by highlighting the esthetic impact of jaw alignment.
