The September 2021 issue of Dermatology Online Journal published an interesting letter that found that dermatology applicants had a higher match rate at their home programs during COVID-19 than in previous years (“The impact of COVID-19 on the dermatology match: an increase in the number of students matching at home programs”), see https://escholarship.org/uc/item/8m77413g
Potential explanations for this observation were limited opportunities for away rotations and the use of virtual interviews that may have favored home applicants.
