随机方法(请说明由何人用什么方法产生随机序列):

在牙体预备导板试验中,将受试者进行编号(1到30,如果拟纳入30名受试者),每个编号受试者由项目组其他人员使用excel软件中【=RANDBETWEEN(1,100)】函数产生随机数(函数意思为随机生成1到100之间的数字),将随机数从小到大进行排序,前15名受试者将被分到实验组,另一半将被分进对照组。

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

In the tooth preparation guide trial, the subjects were numbered (1 to 30, if 30 subjects are to be included), and each numbered subject was generated by other members of the experimental group using the [=RANDBETWEEN(1,100)] function in Excel software (the function means to randomly generate numbers between 1 and 100), and the random numbers were sorted from small to large, and the first 15 subjects will be assigned to the experimental group, and the other half will be divided into the control group.

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:

提前设计病历记录表,包含所有采集的指标。 所有采集的数据录入电脑进行管理和保存,采用双录入的方法,避免录入差错。 采用牛蛙科研(网页地址:https://www.newwa.cn/)作为本研究的临床数据电子采集和管理系统。

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

Design a medical record sheet in advance to include all collected indicators. All collected data is entered into the computer for management and storage, and the method of double entry is adopted to avoid input errors. Newwa Research (webpage address: https://www.newwa.cn/) was used as the electronic clinical data collection and management system for this study.
