Abstract:
Objective: To explore the operating procedure for designing the randomized scheme of multi-center clinical trial. Methods: SAS randomized program was written in accordance with the randomized parameters and stipulated randomized rules of centers, cases and blocks. The design of the SAS randomized program adopts the same seed in multi-hierarchical factors, and the principles of succession and repeatability of the randomized code. Results: This program can produce randomized numbers and complete the design and permutation of randomized codes in a standard and convenient way.
