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 Chronic Kidney Disease

Nephrology trial capacity tracks dialysis infrastructure and biobanking, so the map is dominated by countries with large managed CKD populations. Anyone offered an infusion abroad should note that CKD requires monitored follow-up that a single overseas visit cannot provide.

What travelling for a trial actually involves

Before treating a foreign site as an option, confirm the follow-up burden in writing. Trials measure outcomes on a schedule; missing those visits makes the data unusable and leaves you outside the safety net the protocol provides.

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

Where studies happen reflects who funds and who authorises them. Treating that as a ranking of care quality confuses the research system with the treatment market, two things that overlap far less than medical-tourism marketing implies.

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 (1), 2021 (6), 2022 (3), 2023 (1), 2024 (3), 2026 (4), 2027 (1). Activity for this condition spans 1994 to 2027, which shows whether interest is growing, flat or past its peak.

Frequently asked

Which countries run stem-cell trials for Chronic Kidney Disease?

Sites are registered in 28 countries; the largest is United States (~64% of country mentions, 2026-08-29).

Does a country with many trials mean better treatment there?

It does not follow. A country can host many trials and still have an unregulated commercial sector selling something quite different to visitors.

Are trial sites and commercial clinics the same thing?

Mostly no. Some clinics imply an association with local research institutions; the registry record names the actual sponsor and site, which settles it.
