Body composition was assessed using validated predictive equations and abdominal MRI. The primary outcomes were successful WL (total WL\u00a0\u2265\u00a025%) and DR (fasting glucose\u00a0&lt;\u00a05.6\u00a0mmol\/L and HbA1c\u00a0&lt;\u00a06.0% without antidiabetic medications) during the 3\u00a0year follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Breakpoint analysis indicated that free triiodothyronine (FT3) plateaued beyond an age threshold while showing a linear correlation with fat\u2010free mass index. Higher baseline FT3 tertiles were significantly linked to increased likelihood of achieving successful WL and DR at 1 year follow\u2010up, with stronger associations in females. Optimal FT3 thresholds were identified as 4.75 (females) and 5.05 (males) for WL, and 4.57 (females) and 5.00 (males) for DR. Preoperative FT3 levels below these thresholds were significantly associated with reduced WL and DR over 3\u00a0years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Serum FT3 exhibits an age\u2010related breakpoint effect, and low preoperative FT3, particularly in females, is a critical predictor of suboptimal short\u2010 and long\u2010term WL and DR success post\u2010bariatric surgery.
