We collected, for each active AIGO member, surname, initials of the first name, institutional affiliation (including city), Open Researcher and contributor ID (ORCID). These data were used to identify their published articles, namely research articles, reviews, letters and editorials, from January 1, 1980 to January 20, 2020. Bibliographic research was done using the Web of Science (WOS) database [6] . ORCID and city data were used as search terms only for AIGO members with common names.
