Improving Documentation in Plastic Surgery: Sister Bra Size Group and BMI Are More Indicative of Breast Weight Than Cup Size.

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
backgroundAccurate documentation of breast size is critical for surgical planning, insurance authorization, and research in breast reconstruction. However, breast size is inconsistently recorded, often limited to brassiere cup size, which may not reliably predict breast tissue weight.
objectivesThe authors of this study aim to evaluate whether "sister bra size group"-a previously unverified classification incorporating both bra cup and band sizes-better correlates with breast weight than cup size alone.
methodsA retrospective review was conducted of 209 patients (395 breasts) who underwent mastectomy between 2017 and 2023 at a single institution. Preoperative bra cup and band sizes, mastectomy specimen weights, BMI, and demographic characteristics were recorded. Patients were categorized into sister bra size groups. Spearman's correlation coefficients and multivariate linear regression were used to evaluate associations with breast weight.
resultsSister bra size group showed the strongest Spearman's correlation with breast weight (ρ = 0.76), followed by cup size (ρ = 0.67), BMI (ρ = 0.61), and band size (ρ = 0.48). Age did not have a significant correlation with mastectomy specimen weight (ρ = 0.02). In multivariate analysis, sister size (P = .016) and BMI (P < .001) remained statistically significant predictors of breast weight, whereas cup and band sizes did not.
conclusionsCup size alone is not a reliable predictor of breast tissue weight. Sister bra size groups provide a stronger correlation and a more accurate alternative. Incorporating this variable into clinical documentation may improve preoperative planning and create a more standardized framework for research. LEVEL OF EVIDENCE: 4 (THERAPEUTIC):
