Of 560 cases, 304 met inclusion criteria. Morning TT was measured preoperatively and 6\u201312 months postoperatively. Clinically significant TT elevation was defined as a \u226520% increase from baseline. Receiver operating characteristic (ROC) analysis identified the optimal preoperative TT cut\u2010off for predicting TT elevation, and multivariable logistic regression evaluated independent predictors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The mean age was 69.7 years, and 92 of 304 patients (30.3%) achieved postoperative TT elevation. ROC analysis demonstrated moderate discrimination (AUC 0.737; 95% CI 0.678\u20130.797), with a Youden\u2010optimal TT cut\u2010off of 4.525\u00a0ng\/mL (sensitivity 72.8%, specificity 64.2%). On bootstrap internal validation, the optimism\u2010corrected AUC was 0.738, and the optimal cut\u2010off varied across resamples (95% range 3.13\u20135.07\u00a0ng\/mL), indicating that the threshold is exploratory.
