The full reports have greater detail about the characteristics of who matched.
Urology and ophthalmology hold their own individual Matches are are not included in the NRMP data.
Dermatology is the most competitive specialty, followed by the surgical subspecialties: neurosurgery, orthopedics, ENT, plastic surgery, thoracic surgery and vascular surgery.
PMR has gotten more competitive over the years and is now about as competitive as anesthesia, OB/GYN and general surgery. Emergency medicine has gotten less competitive and is now has about the same selectivity of internal medicine.
Radiation oncology has a high match rate because applicants to this field are highly self-selecting.
MDs match at a higher rate to procedure-based specialties than do DOs. (Probably due to more exposure/experiences during med school.)
