*The search was conducted in two separate phases. Phase one included articles from 2016–2021. In these searches, duplicate articles between databases were removed automatically, prior to screening. For phase two, which included searches for articles from 2022–2024, duplicates were not removed prior to screening. As such, for phase two, duplicates were only accounted for once an article was included following full-text screening.
