3.1.3. Data Extraction in the Screening Stage

All the studies found through the initial search process using the selected keyword strings were incorporated in a master Excel worksheet. In the second stage of screening, first, duplicates were deleted. As the Google Scholar database was algorithmically autogenerated, the duplications needed to be manually deleted by filtering the worksheet. Furthermore, paper exclusions concerning absent or irrelevant title sources (i.e., PowerPoint presentations, white papers, book introductions, calls for papers, competition announcements, and all non-English works) were performed.
