随机方法(请说明由何人用什么方法产生随机序列):

使用分层随机化分组,将合格受试者按1:1的比例分配至干预组与对照组。考虑因素包括年龄、疾病类型、手术难度分级(低、中、高,由外科医师参考DSS-ER肝脏手术难度分级评判)。由与本试验无关的第三方生物统计学家,使用R语言统计软件,为上述每一个分层独立生成一套随机分配序列。

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

Stratified randomization was used to allocate eligible participants to the intervention and control groups in a 1:1. The stratification factors included age, disease type, and surgical difficulty grading (low, moderate, or high), as assessed by the surgeon with reference to the DSS-ER liver surgery difficulty scoring system. An independent biostatistician not involved in this trial generated separate random allocation sequences for each stratum using R statistical software.
