“…The most convincing of these investigations involved approximately 6 [17][18][19][20][21][22] large retrospective cohort studies that followed up patients with breast implants for up to 10 years or longer and detected no increased associated risk of connective tissue disease, such as rheumatoid arthritis, scleroderma, systemic lupus erythematosus, polymyositis/dermatomyositis, Sjögren syndrome, and mixed connective tissue disease. At least 3 of these studies, from the Mayo Clinic (Rochester, Minn), Sweden, and Denmark, aspired to being population based; in the United States, several large studies based on querying female health professionals enrolled up to several hundred thousand subjects each, thus greatly minimizing the risk that even small adverse effects would fail to be detected owing to inadequate sample size.…”
