Figure 4: Relationship between miRNA target site density and SNP density. (a) Variation of SNP density for 5 miRNA target site density groups with increasing density of target sites. The degree of the increasing trend for SNP density along with the increasing density of miRNA target sites was estimated by Wilcoxon rank sum tests and depicted in P values. (b) Variation of miRNA target site density for 5 SNP groups with increasing density. The degree of the increasing trend for miRNA target site density along with the increasing density of SNPs was estimated by Wilcoxon rank sum tests and depicted in P values. Error bars indicate standard errors.
