Layered enhancement at magnetic resonance enterography in inflammatory bowel disease: A meta-analysis

Figure 1 Diagram shows the process for selecting studies that were included in meta-analysis according to PRISMA-2019 guidelines. The twelve articles that were excluded and their reasons for exclusion are listed in Appendix S2[24-32].
