A study with sites in several countries is counted once per country, taken from the location block of each registry record.

What the map means for Anemia

Transplant activity maps onto donor registries, HLA typing capacity and long-term haematology follow-up. Countries with mature bone-marrow donor programmes dominate; this is one of the few areas where trial geography genuinely reflects clinical capability rather than regulatory permissiveness.

What travelling for a trial actually involves

If a site is abroad, the practical questions are who provides follow-up at home, what happens if an adverse event occurs after you fly back, and whether the protocol permits remote assessment at all. Most do not.

Multi-country studies, named

Registered studies with sites in more than one country — the clearest evidence of collaboration rather than a single-centre series.

No sampled study for this condition lists sites in more than one country, so the research base here is made of single-centre work rather than multinational collaboration.

Why trial geography is not a shortlist

The map is drawn by policy and money. Permissive or well-defined regulatory pathways attract registrations and large research budgets attract more still. None of that transfers to the private clinic advertising in the same city, which may operate under no comparable supervision.

Before treating geography as a shortlist, read the legality overview by country and what "best country" actually means here.

When these studies started

Registrations by start year since 2020: 2020 (3), 2021 (4), 2022 (5), 2023 (5), 2024 (10), 2025 (5), 2026 (10), 2028 (2). Activity for this condition spans 1993 to 2028, which shows whether interest is growing, flat or past its peak.

Frequently asked

Which countries run stem-cell trials for Anemia?

Sites are registered in 15 countries; the largest is United States (~75% of country mentions, 2026-08-29).

Does a country with many trials mean better treatment there?

No — trial counts describe where research is permitted and paid for. Care quality is decided at the level of the individual provider and product.

Are trial sites and commercial clinics the same thing?

Rarely. Academic trial sites and the private clinics advertising to medical tourists are typically separate organisations with different oversight.
