IQR, interquartile range.

All comparisons are made with Wilcoxon rank-sum tests.

^aThe h-index was defined as the highest number of an author’s publications that received at least h number of citations.

^bThe m-quotient was calculated by dividing the h-index by the number of years between residency graduation to 2019.
