			Values of PAX1 methylation
	N	Age (Mean ± SE)	Range	(Mean ± SE)
Normal	28	36.1 ± 1.4	0-6.1	3.3 ± 0.41
CIN1	32	38.3 ± 1.3	0-10.2	4.5 ± 0.45
CIN2/3	34	39.7 ± 1.8	0-39.2	13.0 ± 2.2Ψ
Cancer	27	44.4 ± 1.6	0-65.6	26.3 ± 3.5*

^ΨP < 0.001, comparing the CIN2/3 with the Normal and CIN1 groups;

^*P < 0.001, comparing the invasive cancer with CIN2/3 groups.
