随机方法(请说明由何人用什么方法产生随机序列):

根据年龄、种植体植入部位分为不同区组,按区组随机安排进入不同处理组。使用SAS程序生成随机化表,根据随机分组表制作随机化信封。由合作的统计学专家完成。

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

Block randomization with a randomization table generated by SAS software. Conducted by the statistician.

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Scheduled to open the original data by December 2023, the original data can be queried through the Chinese Clinical Trial Registration Center

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:

1.数据库建立、录入和监查:病例报告表(CRF)一经建立,CRF的副本将送交参加本临床试验的数据管理人员统一建立数据。完成的CRF通过临床监查员审查后收回,进行数据处理。 病例报告表的数据采用双人双份录入,在此期间,将有疑问表通过临床监查员转交研究者进行数据审核,研究者尽快回答并返回数据,在盲态审核并经核查确认无误后锁定数据库,锁定后的数据文件不允许再作变动。数据库采用LinkLab(www.mdlinklab.com)。 2.数据处理分析:数据库交统计分析人员按统计计划书要求进行统计分析。统计分析过程实行两次揭盲方法。第一次揭盲在数据锁定后,交统计分析人员进行统计分析时;第二次揭盲在完成统计分析后,并由统计分析人员写出统计分析报告时进行。 3.资料保存:所有与本次临床试验有关的研究资料一经产生,均须在一定时间内存放入特定的资料夹并统一管理。

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

1.Database establishment and censorship: Copies of CRF are sent to set new data once generated, and the data is censored and typed-in once the CRF is completed. All the data is recorded with Linklab(www.mdlinklab.com). 2.Data analysis: completed by specific statisticians, with the principles of two-step ceasing blinding process. 3.Data storage: stored in appointed files and specified time.
