Do We Perform Systematic Literature Review Right? A Scientific Mapping and Methodological Assessment
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-27)Background: Systematic literature review (SLR) is increasingly utilized to maximize the element of rigor and minimize the individual bias of research synthesis. An analysis of the Web of Science (WoS) database indicates that 90% of the literature review studies using SLR have been published between 2012 and 2022. However, this progressive agenda is impaired by the lack of methodological consistency ... -
