The NRMP recently published their Charting Outcomes information for 2022; data I keep bookmarked and which I would recommend applicants review. The reports (for MDs and DOs) separate results into specialties and include extremely helpful information, including what mean board scores, number of contiguous ranks, and number of research experiences were for those who successfully matched - and those who did not.
It's important to make sure you are in the range for your intended field and to compare the competitiveness of different specialties if you are seeking to apply in two fields.
