The difference of the numbers of distance-based, Voronoi-based and <i>β</i> atomic contacts for 114 homodimers and 314 crystal packing.

The numbers in Italics are the difference of the numbers of the contacts under the definitions of its column and row. The number of the last two rows in bold is the number of atomic contacts under the definition of its column. X±Y in last row: X is the mean of the number of atomic contacts in interfaces of a dataset while Y is the standard deviation.
