“Here are some statistics related to sarcoidosis:

• Incidence: Sarcoidosis is most prevalent in Scandinavian and Northern European countries, with a higher risk for Black individuals compared to White individuals in the U.S.².
• Epidemiology: The incidence and prevalence of sarcoidosis vary significantly across populations, with studies indicating that the disease is more common in certain regions and among specific demographics³.
• Patient Demographics: A survey of 1018 US sarcoidosis patients found that 65% were female, 63% White, 34% Black, and 87% were over 45 years old. The most common organs affected were the lungs (87%), skin (30%), heart (25%), and eyes (25%)⁵.

These statistics highlight the heterogeneity of sarcoidosis and its impact on different populations.

High quality and systematically collected data, with depth (detailed information per individual) and breadth (many individuals), is needed to further understand the complexity and heterogeneity of sarcoidosis.
