Comparison of specific DNA methylation sites between women with term and preterm births after pyrosequencing

Variable	Target ID† of differentially methylated site	Term (n = 39)	Preterm (n = 43)	p-value
VTRNA2-1_pos1	cg04481923	25.8 ± 20.9	33.9 ± 18.6	0.065
VTRNA2-1_pos2		26.3 ± 22.2	35.2 ± 19.5	0.045^a
VTRNA2-1_pos3		27.4 ± 22.3	36.4 ± 19.8	0.026^a

Data are presented as the mean ± SD

VTRNA2-1_pos1, _pos2, and _pos3 were analyzed by pyrosequencing as CpG sites of chromosome 5:135,416,205, chromosome 5:135,416,207, and chromosome 5:135,416,214, respectively
