随机方法(请说明由何人用什么方法产生随机序列):

随机分组与设盲按研究中心分层,采用区组随机(区组大小4),1:1分配至侧卧位组或仰卧位组。

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

Randomization is stratified by study center and performed using block randomization with a block size of 4, assigning patients in a 1:1 ratio to either the lateral position group or the supine position 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:

因体位干预无法对操作者设盲,但对结局评估者(记录SpO₂和事件的护士)设盲。

Blinding:

Due to the nature of the positioning intervention, blinding of the operators was not feasible; however, outcome assessors (the nurses recording SpO₂ and events) were blinded to group allocation.
