It is a single-center, provider-authored result, not a general average for all SVF fat grafting, and should be read with its study design.","detailed_answer":"The same study reported 78.65% retention at 3 months (n=384) and 77.17% at 6 months (n=273). Retention was lower in the right breast (60.35%) and in stiff breasts, and higher with more SVF cells. No independent randomized comparison was identified as of September 2026.","format":"paragraph","confidence":75,"verified_at":"2026-09-14 13:42:07","updated_at":"2026-09-14 22:42:08"},"sources":[{"id":27,"title":"A Study on Breast Augmentation Using Fat Grafting With Stromal Vascular Fraction (Shin DJ, Ann Plast Surg 2023;90(4):380-384)","url":"https://pubmed.ncbi.nlm.nih.gov/36881737/","publisher":"Annals of Plastic Surgery","type":"academic","accessed_at":"2026-09-14 13:42:07"}],"published_at":"2026-09-14 13:42:07"}
