Create a new clinical protocol entry in the system.
Standard. Participants are enrolled and followed up after the protocol starts.
Historical data. Enrollment is performed retrospectively from existing databases.
Allocation is performed manually by the study team. No automatic algorithm.
Simple block randomization. Participants are randomly assigned to groups in a fixed ratio.
Optimal balance with respect to clinical factors (age, gender, etc.) across all groups.
Import a pre-defined randomization sequence (Excel/CSV) and validate it against group sizes.
