Comparison of DACH1 methylation in each tissue (n, %).

Group	Number of cases	Methylation	Unmethylation
Cancerous tissue	70	22 (31.43)^ab	48 (68.57)^ab
Paracancerous tissue	70	2 (2.86)	68 (97.14)
Normal tissue	30	0 (0)	30 (100.00)
χ^2 value		29.553
-value		<0.001

Note. Compared with normal tissues, ^a; compared with paraneoplastic tissues, ^b.
