随机方法(请说明由何人用什么方法产生随机序列): |
在获得患者的知情同意后,他们被评估为合格。在计划手术前,由专业统计人员使用计算机生成的随机表将合格患者,按照随机原则 1:1 比例分配到实验组及对照组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Following the provision of informed consent, patients were assessed for eligibility. Eligible patients were then randomly allocated in a 1:1 ratio to either the experimental group or the control group by a statistician using a computer-generated randomization list prior to the scheduled surgery. |

盲法: |
采取“单盲”设计。 术者未设盲;数据分析者已设盲:由未参与手术且对手术程序不知情的研究者负责收集和分析围手术期临床结局指标。 |
|
Blinding: |
A single-blind design was adopted. The operating surgeons were not blinded to group assignment; however, the data analysts were blinded. Perioperative clinical outcomes were collected and analyzed by researchers who were not involved in the surgical procedures and were unaware of the group allocation. |
