随机方法(请说明由何人用什么方法产生随机序列):

参与者将通过区组随机化分配到两个干预组(SDF溶液或SDF凝胶),区组大小为4,6或8。我们的统计学家将生成一个随机序列,并将随机数序列保存在不透明的密封信封中,以隐藏分配序列,直到分配干预措施。

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

The participants will be allocated by block-randomization with a selected block size of 4, 6 or 8 to the two intervention groups (SDF solution or SDF gel). Our statistician will generate a randomisation sequence and maintain the random number sequence in opaque sealed envelopes to conceal the allocation sequence until the interventions are assigned.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

进行口腔检查和临床结果评估的审查员将对儿童的治疗组分配保持不知情。在整个研究过程中,儿童及其父母不会被告知治疗组的安排。

Blinding:

The examiner conducting oral examinations and clinical assessment of outcomes will remain blinded to children's treatment group assignments. Children and their parents will not be informed of treatment group placement throughout the study.

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:

在幼儿园进行口腔检查后,通过病例记录表收集临床资料。此外,还将发放家长报告问卷,收集参与者的背景信息和口腔健康相关行为。一旦数据录入并核查完成,统计人员将加密数据库。纸质表格将被锁在橱柜里,电子文档将被密码保护以保证数据安全。这些数据和信息将在研究结束后保存10年。

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

The clinical data will be collected through case record form after oral examinations in kindergartens. Besides, a parent-reported questionnaire will be distributed to collect participants’ background information and oral health-related behaviours. Once the data are entered and verified, the statistician will lock the database. Paper forms will be kept in locked cabinets, and files will be password-protected to maintain data security. The data and information will be kept for 10 years after the study.
