随机方法(请说明由何人用什么方法产生随机序列):

采用随机分组设计,将实验组与对照组按照1:1进行分配。 随机数字表由计算机生成表格( http://www.randomizer.org/)自动创建一个序列,为每一个病例分配一个识别号,术前告知术者分组情况。保证临床试验中每位受试者均有同等机会被分配到试验组或对照组,不受研究者和/或受试者主观意愿的影响。

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

The study employed a randomized group design, with the experimental and control groups allocated in a 1:1 ratio. The random number table is a computer-generated table (http://www.randomizer.org/) that automatically creates a sequence, assigns an identification number to each case, and informs the surgeon of the grouping before surgery. Ensure that each subject in the clinical trial has an equal chance to be assigned to the experimental group or the control group, regardless of the subjective will of the investigators and/or the subjects.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

据受试者的原始观察记录,保证将 数据正确、完整、清晰、及时地载入病例报告表。修改时需保持原有记录清晰可见,改正处需经 研究者签名并注明日期。不允许用刀刮去或用改正液涂去原始记录病例报告表。 数据来源包括:临床病例记录、照片记录、CBCT。在临床试验手工录入前,应确认完整的临床研究数据来源及采集范围,记录时抹去患者隐私。数据录入电子系统后保持备份,并定期由主研究者审核。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Based on the original observation records of the subjects, ensure that the data is correctly, completely, clearly, and promptly recorded in the case report form. When making modifications, the original records must be kept clear and visible, and any corrections must be signed and dated by the researcher. It is not allowed to scrape or apply correction fluid to the original recorded case report form with a knife. The data sources include: clinical case records, photo records CBCT。 Before manually entering clinical trials, the complete source and scope of clinical research data should be confirmed, and patient privacy should be erased when recording. After data is entered into the electronic system, it should be backed up and regularly reviewed by the lead researcher.
