The flow diagram is split into two main vertical sections labeled “Primary Data” on the left and “Secondary Data” on the right, with three horizontal stages. These stages are labeled within three text boxes arranged in a vertical series on the left. From top to bottom, the text boxes are labeled as follows: “Identification”, “Screening”, and “Include”. “Primary Data” Section: The first textbox in the “Identification” is labeled “Records identified from” lists sources and counts as follows: “Scopus 313, ScienceDirect 133, Emerald Insight 127, SpringerLink 129, and Google Scholar 8; Total 710”. A rightward arrow points from the first to the second text box, positioned at the same level and stage, labeled “Records removed before screening” with reasons listed as follows: “Non-Engineering Literature, non-building construction, government funding, irrelevant standard (n equals 612), Non-English articles (n equals 2)”. A downward arrow points from the first to the third text box positioned directly below in the “Screening” stage. The text box is labeled “Records screened (n equals 96)”. A rightward arrow points from here to the fourth text box positioned at the same level and stage, labeled “Not discussed W L C or L C C-related frameworks (n equals 67)”. A downward arrow points from the third text box to the fifth one positioned directly below at the same stage, labeled “Reports sought for retrieval (n equals 29)”. A rightward arrow points from here to the sixth text box positioned at the same level and stage, labeled “Reports not retrieved, remove duplicates (n equals 7)”. A downward arrow points from the fifth to the seventh text box positioned directly below in the same stage. The text box is labeled “Reports assessed for eligibility (n equals 22)”. A rightward arrow points from here to the eighth text box positioned at the same level and stage, labeled “Reports excluded: (n equals 10): Articles without Authors, Related to prefabricated house or off-site construction, Related to automobile, Non-availability of full text”. A downward arrow points from the seventh to the ninth text box positioned directly below in the “Include” stage. The text box is labeled “Primary search reports (n equals 12); Secondary search reports (n equals 39); Total (n equals 51)”. “Secondary Data” Section: The tenth text box is positioned in the “Identification” stage and is labeled “Records identified from: Secondary research data (n equals 69). A rightward arrow points from this box to the eleventh text box, positioned at the same level and stage, labeled “Removed: Inadequate relevance (n equals 30)”. A downward arrow points from the tenth text box to the twelfth text box positioned in the “Screening” stage, on the right side of the eighth text box, and is labeled “Reports assessed for eligibility (n equals 39)”. A downward arrow points from the twelfth text box to the ninth text box in the “Include” stage of the “Primary Data” section.PRISMA flow diagram adapted from PRISMA 2020 statement. Page et al. (2021)
