随机方法(请说明由何人用什么方法产生随机序列): |
由研究计划的数据统计分析员或数据管理人员负责,并确保后续的随机分组的过程是可追溯和透明的。采用硬币抛掷的方式将患者随机分配到治疗组。首先,抛硬币来确定治疗组的分配,硬币的一面决定了每种治疗的分配(比如:正面:“冠向复位信封瓣+CTG”组,反面:“冠向复位隧道瓣+CTG”组)。随后,再次抛硬币将患者随机分配到相应的治疗组中。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The responsibility for data analysis and management of the research project lies with the data statistician or data management personnel, ensuring that the subsequent randomization process is traceable and transparent. Patients are randomly assigned to treatment groups using a coin-toss method. Initially, a coin is flipped to determine the allocation of the treatment group, with one side of the coin determining the assignment for each treatment (e.g., heads: "crown-advancement repositioned flap + CTG" group, tails: "crown-advancement tunnel flap + CTG" group). Subsequently, the coin is flipped again to randomly assign patients to their respective treatment groups. |

盲法: |
双盲:使得接受干预的患者也不知道自己属于试验组还是对照组,同时治疗团队(医生、护士等)也不知道患者的具体分组。 分组信息保密:将患者的分组信息(接受“冠向复位信封瓣”或“冠向复位隧道瓣”)保密,确保患者在手术前、手术中和手术后的过程中都不知道自己属于哪个组; 使用虚拟标签:使用虚拟的标签或编号来标识手术材料,以使治疗团队无法直接识别患者的分组。例如,可以用字母或数字代替实际的手术方法标签; 处理主观评价的盲法:如果研究涉及主观评价,如疼痛感知、术后愈合等,确保对这些评价的进行也是盲的,即评价者不知道患者的分组信息; 培训研究团队:确保研究团队成员,包括医生、护士和其他涉及患者照顾和数据收集的人员,接受盲法培训,以保障盲法的执行; 监控执行过程:定期监控盲法的执行过程,以确保其符合预定的计划。这包括监测患者分组信息的保密性和评价者对患者分组的无知状态。 由于本研究是两种手术方式的研究,手术医生可能无法完全盲化,因为他们需要知道实际进行的手术步骤。在这种情况下,尽管手术医生不太可能完全双盲,但可以采用一些策略来最大程度地降低他们的主观偏见: 数据评估的盲法:手术医生可能无法盲化手术操作,但在收集和评估研究结果时,可以采用盲法。例如,对于一些主观评价指标,比如术后愈合的外观,可以由独立的评估者进行评价,而这些评估者并不知道患者接受的具体手术方式; 结果数据处理的盲法:手术医生在术后提供的手术报告和病例资料中,可以对手术方式的标识进行处理,以保持某种程度的盲法。例如,在报告中使用编号代替实际的手术方式,以便在分析结果时医疗团队不知道每个患者接受的确切手术方式; 医生培训和认知偏见的管理:在研究开始之前,对手术医生进行适当的培训,明确他们在手术中的角色以及研究的盲法要求。强调他们在手术中不要透露分组信息,以减少潜在的认知偏见; 术后照顾的标准化:尽量标准化术后的照顾流程,确保所有患者接受相似的术后护理和随访,以减少由于手术医生的认知偏见而引起的影响。 |

Blinding: |
Double-blind: Patients receiving intervention are unaware of whether they belong to the experimental or control group, and the treatment team (doctors, nurses, etc.) is also unaware of the specific patient grouping. Confidentiality of grouping information: Maintain secrecy of patient grouping information (receiving "coronary reset envelope flap" or "coronary reset tunnel flap") to ensure that patients are unaware of their group assignment before, during, and after surgery. Use of virtual labels: Employ virtual labels or numbers to identify surgical materials, preventing the treatment team from directly identifying patient groups. For example, use letters or numbers instead of actual surgical method labels. Blinding subjective assessments: If the study involves subjective assessments such as pain perception or postoperative healing, ensure that these assessments are also blinded, meaning assessors are unaware of patient grouping information. Team training: Ensure that team members, including doctors, nurses, and others involved in patient care and data collection, undergo training in blinding methods to ensure the execution of blinding. Monitoring the execution process: Regularly monitor the execution of blinding procedures to ensure compliance with the predetermined plan. This includes monitoring the confidentiality of patient grouping information and the unaware status of assessors regarding patient grouping. Given that this study involves two surgical methods, surgeons may not be able to achieve complete blinding as they need to know the actual surgical steps. In such cases, although surgeons are less likely to achieve complete blinding, strategies can be employed to minimize their subjective bias to the greatest extent possible: Blinding of data assessment: Surgeons may not blind the surgical procedure, but blinding can be applied during the collection and evaluation of study results. For example, for subjective assessment indicators such as the postoperative appearance of healing, independent assessors unaware of the specific surgical method received by each patient can conduct the evaluations. Blinding of outcome data processing: In postoperative reports and case records provided by surgeons, identification of the surgical method can be processed to maintain a certain degree of blinding. For instance, using numerical codes instead of actual surgical methods in reports ensures that the medical team remains unaware of the exact surgical method each patient received during result analysis. Physician training and management of cognitive bias: Prior to the study commencement, provide appropriate training to surgeons, clarifying their roles in surgery and the blinding requirements of the study. Emphasize the importance of not revealing grouping information during surgery to minimize potential cognitive biases. Standardization of postoperative care: Strive to standardize postoperative care processes, ensuring that all patients receive similar postoperative care and follow-up, reducing the impact of cognitive bias due to surgeon knowledge. |
