Scoping reviews are a "preliminary assessment of potential size and scope of available research literature. Aims to identify nature and extent of research evidence (usually including ongoing research)." Grant and Booth (2009).
Requires fewer data sources and doesn't require assessing individual studies for risk of bias.
Often a scoping review is confused with a mapping review. They are not systematic reviews, but the methodology is closely related.
