h-Index has been proposed as a useful bibliometric measure for quantifying research productivity. In this current study, we analyzed h-indices of editorial board members of Radiology journals and tested the hypothesis that editorial board members of Radiology journals with higher impact factors (IF) have higher h-indices.Materials and MethodsSixty-two Radiology journals with IF >1 were included. Editorial board members were identified using the journals' websites. Editors' affiliations and research fields of interest were used to distinguish investigators with similar names. Bibliometric indices including number of publications, total citations, citations per publication, and h-index for each editorial board member were obtained using the Web of Science database. Chi-square or Wilcoxon rank-sum tests were used to test for differences in bibliographic measures or demographics between groups.ResultsAmong the editorial boards of 62 journals, the median [interquartile range] board h-index was 26 [18, 31] and had 36 [17, 56] members. The median journal IF was 2.27 [1.74, 3.31]. We identified a total of 2204 distinct editors; they had a median [interquartile range] h-index of 23 [13, 35], 120 [58, 215] total publications, 1938 [682, 4634] total citations, and an average of 15.7 [9.96, 24.8] citations per publication. The boards of journals with IF above the median had significantly higher h-indices (P = .002), total publications (P = .01), and total and average citations (both any [P = .003, .009] and nonself-citations [P = .001, .002]) than journals below the median.ConclusionsOur data indicate that board members of Radiology journals with higher IF have greater h-indices compared to lower IF journals.
