Breakdown of the three CTCF score-based classes for sites either unique to CD4+ T cells or shared with one or more other cell types. The three additional human cell types considered are HeLa, Jurkat, and IMR90. For instance, if a CTCF site is occupied in CD4+ T cells and exactly one of the other three cell types, it is included in the 'CD4+ plus one' category. The bar titled 'CD4+ ALL' refers to all CTCF sites identified in the CD4+ T cells.
