Multivariate Cox regression analysis in male TC patients.

	Multivariate analysis
	p-value	HR (95% CI)
ASF1B (High expression level vs. Low expression level)*	0.001	7.823 (2.266–27.013)
Age (>60 vs. ≤60)	0.928	0.943 (0.266–3.339)
Histological type (NON PTC vs. PTC)**	0.988	0.001 (0.001–∞)
Tumor size (T3–4 vs. T1–2)	0.552	1.481 (0.406–5.406)
Lymph node status (N1 vs. N0&Nx)	0.447	0.637 (0.201–2.034)
Metastasis (M1 vs. M0&Mx)	0.629	1.717 (0.192–15.361)
Pathological stage (S3–4 vs. S1–2)	0.098	3.666 (0.787–17.072)
Extent of the primary tumor (Single lobectomy vs. Multiple lobectomies)***	0.451	6.937 (0.449–6.038)

Tumor stage (T), lymph node metastasis stage (N), and metastasis (M) were divided into two groups according to the 8th American Joint Committee on Cancer (AJCC) editions. *Grouped according to the best cutoff points determined by the ROC curve. **PTC, Papillary thyroid carcinoma. ***In thyroid surgical practice, the thyroid is divided into three anatomical zones, the left lobe, right lobe, and thyroid isthmus.
