Table 4.
Numbers and percentages of observed DFIs for all pairs of DFBS SSE classes in our dataset of 3084 DFIs. In parentheses is the number of DFIs expected if the binding occurs randomly between any two SSE classes of DFBSs. Statistical testing identifies percentages that are significantly higher (bold) or lower (underlined) than the percentages expected from random binding.
