随机方法(请说明由何人用什么方法产生随机序列):

本研究采用区组随机化和分层随机化方法,采用计算机软件(如SPSS)生成随机分配列表,确保不同年龄层次的受试者在实验组和对照组中的均衡分布。

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

This study adopts the methods of block randomization and stratified randomization. Computer software (such as SPSS) is used to generate a random allocation list to ensure the balanced distribution of subjects of different age groups between the experimental group and the control group.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

由于禁食策略涉及受试者的饮食行为,受试者及其监护人难以保持盲法,因此采用单盲试验设计,即评估胃内容物的研究者对受试者的分组情况保持不知情,以减少观察者偏倚。

Blinding:

Since the fasting strategy involves the dietary behaviors of the subjects, it is difficult for the subjects and their guardians to maintain the blind method. Therefore, a single-blind trial design is adopted, that is, the researchers evaluating the gastric contents remain unaware of the grouping of the subjects, so as to reduce observer bias.
