DSS curves of multivariate Cox analysis in the group with tumors >2 cm. DSS is based on radioactive isotope in (A) patients with intrathyroidal extension; (B) patients with minimal extrathyroidal extension; (C) patients with gross extrathyroidal extension; (D) patients younger than 45 years; (E) patients older than 45 years; (F) patients without lymph node metastases; (G) patients with lymph node metastases; (H) patients without distant metastases; (I) patients with distant metastases.

Abbreviations: aHR, adjusted hazard ratios; DSS, disease-specific survival.
