Clinical data and events of interest were identified through linkages with prospectively maintained nationwide and institutional registries. Hazard ratios (HRs) for autoimmune and rheumatic diseases were calculated using Cox proportional hazards regression models adjusted for potential confounders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 12\u2009262 women in the cohort, 3082 (25%) had received silicone breast implant\u2013based breast reconstructions. Median follow-up time was 12.0 years (IQR = 7.0 years). The event rate of autoimmune and rheumatic disease diagnoses was 62.5 per 10\u2009000 person-years. Compared with women without silicone breast implant exposure, women with an implant-based breast reconstruction did not have an increased risk of autoimmune and rheumatic diseases (multivariably adjusted HR = 1.06, 95% CI = 0.89 to 1.27). In addition, no statistically significant association was found between silicone breast implant exposure and inflammatory arthritis, systemic rheumatic disease, inflammatory dermatosis, inflammatory bowel disease, or any specific condition. Sensitivity analyses in which silicone breast implant exposure was analyzed as a time-dependent variable confirmed the results of the main analysis.<\/jats:p>\n                  <\/jats:sec>\n
