随机方法(请说明由何人用什么方法产生随机序列):

本着可实行性的原则,按抽取随机数的方法进行了随机分组,具体实施方案为:招募受试者者后现场抽取三位数的随机数作为本次实验的编号,在所有受试者登记完成后,由另外由2名独立研究究员对随机数进行1:1分组,分组原则采取单双数原则,并通过现场抽签方式决定左旋精氨酸组和安慰剂组。

Randomization Procedure (please state who generates the random number sequence and by what method):

In accordance with the principle of feasibility, random grouping was performed according to the method of extracting random numbers. The specific implementation is as follows: after recruiting subjects, a three-digit random number is selected on the spot as the number of this experiment. After the registration was&
