随机方法(请说明由何人用什么方法产生随机序列):

招募的参与者由外部试验合作者使用基于计算机的随机整数生成器(Research Randomizer, www.randomizer.org)按1:1的比例随机分配到两组。分配结果被放入按顺序编号的、不透明的密封信封中,在手术当天打开。

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

The recruited participants were randomly assigned in a 1:1 ratio to the two groups by external trial collaborators using a computer-based random number generator (Research Randomizer, www.randomizer.org). The allocation results were placed in sequentially numbered, opaque sealed envelopes and were opened on the day of the surgery.

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:

患者分配结果被放入按顺序编号的、不透明的密封信封中,在手术当天打开。没有镇痛药提供者或护士参与本试验。除主刀医生外的外科医生、结果评估者、数据分析师和患者都对干预措施不知情。

Blinding:

The patient allocation results were placed in numbered, opaque sealed envelopes and were opened on the day of the surgery. No anesthesiologist or nurse was involved in this trial. Surgeons other than the lead surgeon, result evaluators, data analysts, and patients were all unaware of the intervention measures.
