The flowchart illustrates the process of databases review. The process begins with the identification phase where records are identified from four databases: Scopus, ScienceDirect, IEEE Xplore, and Web of Science. A total of 183 records are identified. Duplicate records, totaling 33, are removed before screening. This leaves 150 records to be screened. Out of these, 129 records are excluded. Reports are sought for retrieval for the remaining 21 records. Two reports are not retrieved, leaving 19 reports assessed for eligibility. Seven reports are excluded, resulting in 12 studies included in the review.Database search process based on PRISMA template. Source: Authors’ own work
