Payment can mean different things
A study may offer a fixed payment, reimbursement for travel, payment per visit, or no payment at all. Ask whether payment depends on completing every visit and what happens if you withdraw.
Compensation should not pressure you
Participation is voluntary. Payment should not make you feel unable to say no, ask more questions, or stop participation according to the consent rules.
Check the practical details
Before joining a paid clinical trial, ask about visit length, travel, tax paperwork, payment timing, missed visits, privacy, risks, and who to contact with questions.
