研究目的: |
(1)比较 Class I、Class II、Class III 不同矢状骨型患者在拔牙正畸治疗后的软组织三维变化模式; (2)提取具有临床诊断和预测价值的软组织三维特征参数; (3)探索骨型差异化的软组织响应机制,为面型变化的个体化预测模型构建提供依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
(1) To compare the three-dimensional soft-tissue change patterns after extraction-based orthodontic treatment among patients with different sagittal skeletal patterns (Class I, Class II, and Class III); (2) To identify three-dimensional soft-tissue parameters with clinical diagnostic and predictive value; (3) To elucidate skeletal pattern–specific soft-tissue response mechanisms, thereby providing a basis for constructing individualized predictive models of facial profile changes. |

是否共享原始数据: IPD sharing |

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址): |
本研究不在公开网络数据库上发布原始CBCT与三维面扫影像,仅在去标识化处理后共享测量数据与分析代码。拟在主要研究结果发表于同行评议期刊后1年内,接受符合条件的研究者通过电子邮件向课题负责人提出书面申请,经本单位伦理委员会及课题组审核通过后,由课题负责人通过医院科研数据管理平台或加密云盘点对点提供去标识化数据集、变量说明及统计分析脚本。 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
Individual participant data (IPD) will not be deposited in an open web-based public database. Only de-identified measurement data and analysis codes will be shared. Within 1 year after publication of the main study results in a peer-reviewed journal, qualified researchers may submit a written request to the principal investigator via e-mail. Upon approval by the institutional ethics committee and the study team, de-identified datasets, data dictionaries and statistical analysis scripts will be provided through the secure research data management platform of Peking University Hospital of Stomatology or an encrypted cloud service on a case-by-case basis. |
|
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: |
本研究采用统一设计的病例报告表(CRF)进行数据采集,包括受试者一般信息、诊断与治疗信息、CBCT与三维面扫影像编号及各测量变量等。影像测量由经过培训的研究者在三维影像软件中完成,测量结果以受试者唯一识别码记录于CRF,并由两名研究者采用双人独立录入的方式,将数据录入加密的电子数据库(如Excel/院内科研数据管理系统),通过逻辑核查和随机抽查比对纠正录入错误。 所有电子数据存放于医院受限访问的服务器或加密硬盘,设置权限管理和定期备份,仅限课题组授权成员访问;纸质CRF存放于锁柜内,与任何含有受试者姓名、病历号等身份信息的文件分开保存,通过编号实现去标识化。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
A standardized case report form (CRF) will be used to collect data, including basic demographic and clinical information, diagnostic and treatment records, IDs of CBCT and 3D facial scans, and all measurement variables. Image measurements will be performed in dedicated 3D imaging software by trained investigators, and the results will be recorded in the CRF using unique study IDs instead of personal identifiers. Data will be entered into an encrypted electronic database (e.g., Excel or the institutional research data management system) by two independent researchers with double data entry. Logical checks and random audits will be conducted to identify and correct inconsistencies. Electronic data will be stored on password-protected institutional servers or encrypted hard drives with restricted access and regular backup. Paper CRFs will be kept in locked cabinets, separately from any documents containing identifiable information (such as names or hospital IDs), and de-identification will be ensured by using study IDs throughout data processing and analysis. |
