    A nomogram was developed to predict central lymph node metastasis (CLNM) in patients with unifocal papillary thyroid microcarcinoma (PTMC).

  • 2

    Key independent risk factors for CLNM include age ≤38 years, tumor size >0.95 cm, microcalcifications, and specific tumor locations.

  • 3

    Hashimoto's thyroiditis was identified as a protective factor against CLNM in patients with unifocal PTMC.

  • 4

    The nomogram achieved AUCs of 0.772 in training and 0.728 in validation, indicating strong predictive discrimination.

  • 5

    This tool aids in preoperative assessment, enhancing surgical planning and reducing the risk of overtreatment in unifocal PTMC.
