Pens and vouchers: can small rewards boost participation in blood cancer research?
NCT ID NCT01831635
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Researchers want to learn what causes myeloproliferative neoplasms, a group of rare blood cancers. They are testing whether small incentives like pens, trolley tokens, or a £10 reimbursement encourage more people to join a case-control study. The trial includes about 100 patients with these cancers and 200 healthy controls. The goal is to find the best ways to recruit participants for a larger UK-wide study.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Small incentives such as branded pens, trolley tokens, and a £10 reimbursement
- What this could lead to
- If successful, this could help researchers design larger studies that uncover what causes myeloproliferative neoplasms, potentially guiding prevention.
- What could go wrong
- This is an early, small study focused on recruitment methods, not on finding causes or treatments. It may not improve participation enough to justify a larger study.
