Rank correlations (ρ) and partial rank correlations (ρ_p) of the examined genomic properties with expression dissimilarities (measured by ExpD _{1- r} or ExpD _Euc) of the 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	0.039 (0.164)	-0.011 (0.707)	0.100 (<10-3)	0.021 (0.461)
#CTCF	0.111 (<10-4)	0.103 (<10-3)	0.187 (<10-10)	0.159 (<10-7)
ΔCpG O/E	0.069 (0.015)	0.054 (0.023)	0.102 (<10-3)	0.094 (<10-3)

^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
