随机方法(请说明由何人用什么方法产生随机序列):

研究者利用SPSS 26.0 (IBM)软件输入1~200作为入组顺序编号,生成200个对应的随机数,并将随机数按大小平均分成两组,规定随机数较大的组为PSV组,另一组为T管组,这样就生成了入组顺序对应的随机分组。

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

The researchers used SPSS 26.0 (IBM) software to input 1~200 as the sequence number of inclusion, generated 200 corresponding random numbers, and divided the random numbers into two groups according to the size. The group with the larger random number was defined as PSV group, and the other group was

盲法:

由于PSV组和T管组具体操作不同,难以在试验的各个环节对受试者、研究者施盲。故本试验不采用盲法。

Blinding:

Due to the different specific operations between PSV group and T-piece group, it is difficult to blind the subjects and researchers in all aspects of the trial. Therefore, blinding was not used in this study.
