               [Abstract] Objective:To identify risk factors for level Ⅱ and level Ⅳ lymph node metastasis in papillary thyroid carcinoma(PTC)
                and to evaluate the predictive value of different tumor location classification methods. Methods:A retrospective analysis was performed
                on PTC patients who underwent thyroid surgery between January 2022 and May 2025. Clinical and pathological variables were
                collected. Tumor location was classified using the conventional longitudinal trisection method and a middle thyroid vein⁃based method
                on preoperative contrast⁃enhanced CT images. Univariate and multivariate logistic regression were used to analyze factors related to
                level Ⅱ and Ⅳ lymph node metastasis,and ROC curves were used to compare the predictive ability of different tumor location
                classifications. Results:Among 152 patients,59(38.82%)had level Ⅱ lymph node metastasis and 113(73.34%)had level Ⅳ lymph
                node metastasis. Univariate analysis revealed that tumor location was significantly associated with metastasis in both levels(P < 0.05).
                Multivariate analysis showed tumor location(conventional or middle vein⁃based)independently predicted level Ⅱ metastasis,while
                middle vein⁃based location and level Ⅵ metastasis independently predicted level Ⅳ metastasis. ROC analysis showed that the middle
