Methodology

The results of the Advanced search in Scopus were restricted by an algorithm with

• a time period of publishing (2010 to 2016)
• the document types (articles or reviews),
• and a quantitative limitation regarding the publication output (articles by the 20 highest performing authors with the most Scopus listed articles in every subject area).
