随机方法(请说明由何人用什么方法产生随机序列):

采用分层区组随机化方法。以年龄(<=28岁 vs >28岁)和BMI(<24 kg/m^2 vs >=24 kg/m^2)为分层因素,共4层。每层内由独立统计人员使用计算机生成区组长度为4的随机序列,按1:1比例分配至干预组和对照组。分配方案装入密封不透光信封实现隐藏。受试者完成基线评估后,独立负责人根据其分层打开对应信封,告知干预实施者分组结果。

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

A stratified block randomization method will be employed. Stratification factors include age (<=28 years vs. >28 years) and body mass index (BMI) (<24 kg/m^2 vs. >=24 kg/m^2), resulting in a total of four strata. Within each stratum, an independent statistician will use computer-generated random sequences with a block size of 4 to allocate participants in a 1:1 ratio to either the intervention group or the control group. The allocation scheme will be concealed using sealed, opaque envelopes. After completing baseline assessments, an independent personnel will open the corresponding envelope based on the participant's stratification category and inform the intervention implementers of the group assignment.

盲法:

本研究为评估者盲的随机对照试验,受试者及干预指导人员均知晓分组(受试者进入不同氧浓度氧舱,干预人员需操作设备设置参数)。结局评估人员不参与分组与训练指导,对分组保持盲态。

Blinding:

This was an assessor?blind randomized controlled trial. Participants and interventionists were not blinded to group allocation, as participants were exposed to different oxygen concentrations in the chamber and interventionists were required to operate the equipment and adjust the parameters accordingly. Outcome assessors, however, were not involved in group assignment or training supervision and remained blinded to group allocation throughout the trial.
