Over 80% of patients completed participation in RCTs more than one year ago. 71.6% of patients participated in more than one RCT.

In cases where patients answered dichotomous questions (such as "yes"/"no"), the overwhelming majority of patients (74%) claimed that it was the authority of the doctor of the scientific center and the fear of losing the possibility of further observation became the main reason for participating in RCTs.Conclusion.
