Rank correlations (ρ) and partial rank correlations (ρ_p) of the genomic properties with expression dissimilarities (measured by ExpD _{1- r} or ExpD _Euc) of the non-paralogous adjacent genes

Genomic properties a	ExpD 1-r		ExpD Euc
	ρ ( P -value) b	ρ p ( P -value) b,c	ρ ( P -value) b	ρ p ( P -value) b,c
d	0.180 (<10-217)	0.130 (<10-113)	0.112 (<10-83)	0.040 (<10-11)
#CTCF	0.120 (<10-98)	0.032 (<10-7)	0.104 (<10-72)	0.058 (<10-22)
ΔCpG O/E	0.077 (<10-39)	0.049 (<10-16)	0.196 (<10-258)	0.182 (<10-227)

^a "d", intergenic distance; "#CTCF", number of overlapping CTCF-binding sites; "ΔCpG _O/E", difference in upstream DNA methylation.

^b P values show the probabilities of the observations under the hypothesis of no correlation.

^c Spearman's partial correlation coefficient ρ_p is computed by controlling for the other two genomic properties listed in ^a
