The number of articles resulting from the search in the whole PubMed database for the given time periods, for publications in English language based on the given text words. The search terms were chosen at our discretion but we tried to minimize the author bias by including multiple diverse terms. The results for each search do not exclude the remaining strings, and hence, the same paper may be counted towards different search results
