Breast Volume Measurements and Objectivations for Determination of Symmetry: A Retrospective Study in a Large Study Population.

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
backgroundBreast symmetry plays a key role in breast reconstructive surgery. In the healthy population, volume asymmetry is common. This study aimed to better understand how breast symmetry is perceived and to compare subjective estimation with objective measurements of breast symmetry in the healthy participants.
methodsA retrospective cross-sectional study included healthy participants who underwent VECTRA 3-dimentional breast imaging. Breast volume measurements were obtained using the VECTRA system. Five plastic surgeons and five laypersons assessed volume symmetry subjectively.
resultsOf 209 healthy participants, 100 were randomly selected for assessment. Mean left and right breast volumes were 636.8 cc and 664.8 cc, respectively, with a mean relative volume difference of 16.0% (SD 12.7). No clear threshold of relative breast volume difference was found in which the majority of plastic surgeons or laypersons defined breast asymmetry. Even with large volume differences quantified by 3D VECTRA measurement, breasts were perceived as symmetrical by both plastic surgeons and laypersons. Inter-observer agreement was poor for both groups (Fleiss' kappa: surgeons 0.23; laypersons 0.30). Agreement with 3D measurements regarding the larger breast was low (surgeons: accuracy 53.8%, Cohen's kappa 0.08; laypersons: accuracy 48.6%, Cohen's kappa -0.07).
conclusionsSubjective assessments of breast symmetry by both experts and laypersons poorly correlate with objective 3D imaging volume measurements. Symmetry perception likely extends beyond volume alone, influenced by factors such as breast shape, projection, and nipple position. While 3D imaging provides reliable volume measurements and preoperative consultations, it alone may not enhance patient satisfaction regarding perceived symmetry.
