Limbs were categorized into IPV-positive and IPV-negative groups based on duplex ultrasonography. Clinical severity was assessed using the Clinical-Etiological-Anatomical-Pathophysiological (CEAP) classification. Multivariable logistic regression and receiver operating characteristic (ROC) analysis were performed to identify predictors of IPV presence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 192 limbs, IPVs were identified in 102 (53.1%).

ROC analysis revealed an optimal cutoff for SFJ diameter of 7.75\u00a0mm for predicting IPV (Area Under the Curve [AUC]: 0.646; sensitivity 65.0%, specificity 65.2%).
