随机方法(请说明由何人用什么方法产生随机序列):

在本次研究中,我们使用了计算机软件来生成随机数字序列。该过程由独立的第三方统计员执行,他们不参与患者的筛选、纳入或后续的数据收集。具体而言,我们使用了R语言的"sample"函数来生成随机数字,该函数能保证生成的数字序列具有良好的随机性。每个患者被分配了一个唯一的ID,然后根据随机数字序列被分配到相应的组别。

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

In this study, we utilized computer software to generate random number sequences. The process was performed by independent third-party statisticians who were not involved in patient screening, enrollment, or subsequent data collection. Specifically, we employed the "sample" function in the R programming language to generate random numbers, ensuring the generated sequence possessed good randomness. Each patient was assigned a unique ID and then allocated to the corresponding groups based on the random number sequence.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

在我们的实验中,没有采用盲法。这是由于我们的实验设计和操作流程的特殊性。具体来说,我们的实验涉及到药物和运动联合干预,这两种干预方式在实际操作中难以进行模拟或隐藏。此外,我们的主要结果指标是血液代谢及骨骼肌磁共振指标,这些指标的测量结果是客观的,不受实验者或患者知道分组情况的影响。因此,即使没有使用盲法,我们的实验结果也不太可能受到实施偏倚或测量偏倚的影响。

Blinding:

In our experiment, blinding was not employed due to the specific nature of our experimental design and procedures. Specifically, our study involved a combined intervention of medication and exercise, both of which are challenging to simulate or conceal in practice. Additionally, our primary outcome measures are blood metabolic and skeletal muscle magnetic resonance imaging (MRI) indicators, which provide objective measurements unaffected by the knowledge of group allocation by experimenters or participants. Therefore, even in the absence of blinding, it is unlikely that our experimental results would be significantly influenced by implementation or measurement biases.
