These are comparing the 2012 PD survey to the 2014 one for the percentage of programs that would interview and rank DO applicants. Keep in mind that most of these changes may be within the margin of error - I didn't look that closely at the report to compare (for example for the rare residencies, the % changes are more pronounced, but that could be simply because those have a greater margin of error due to their small population size - e.g. RadOnc, Vasc Surg, etc.):
