Using Student's t-test revealed that all values are significantly different although for the plus-strand coded promoters (in Figure 5b ) the middle-range promoter-cis values (the 301–450 range promoters paired with the 301–450 range cis elements) have only a marginally significant (p-value = 0.023) difference when compared to the 601–750 range promoters paired with the 301–450 range cis elements (i.e. middle orange bar vs. the middle purple bar in Figure 5b ).
