Core Tip
Core Tip: This scoping review demonstrates the lack of epidemiologic data on Crohn’s disease in low and lower-middle income countries, but that it does exist in these settings and presents unique challenges. There is a need for population-based research to fully understand the its burden among the world’s poorest people.
