研究目的:

本项目立足“近视防控”战略需求,聚焦进展性近视,针对具有低度近视高危因素的儿童青少年,探索儿童近视防控最佳使用角膜塑形镜方案,寻找治疗与疗效评价的关键预测指标和规律,探究控制近视潜在机制,为预防儿童近视提供精准化的防治方案和临床决策。  

Objectives of Study:

This project is based on the strategic needs of "myopia prevention and control", focuses on progressive myopia, and aims at children and adolescents with risk factors for low myopia. It explores the optimal application scheme of corneal (orthokeratology lenses) for myopia prevention and control in children, searches for key predictive indicators and patterns of treatment and efficacy evaluation, explores the potential mechanism of myopia control, and provides precise prevention and treatment schemes and clinical decisions for the prevention of childhood myopia.

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):

本研究承诺在试验结束后6个月内开放原始数据访问。原始数据存储于海军军医大学卫生统计学办公室的ISO 27001认证服务器,采用AES-256加密技术。所有数据访问均记录日志,严禁将数据用于商业目的或再次共享。

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

This study commits to making the raw data accessible within 6 months after the completion of the trial. The raw data is stored on the ISO 27001-certified servers of the Office of Health Statistics at Naval Medical University and encrypted using the AES - 256 encryption technology. All data access is logged. The use of data for commercial purposes or re - sharing is strictly prohibited.

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:

数据采集:本研究采用电子化与纸质记录相结合的方式。数据录入与管理由统计单位数据管理员负责,采用EpiData数据库进行数据录入与管理。为保证数据的准确性,由两个数据管理员独立进行双份录入并校对。纸质CRF用于记录不良事件及病史信息。眼轴长度使用IOL-MASTER 700测量仪测定,视力检测采用标准对数视力表,由专业验光师操作。 数据管理:在确认所建的数据库无误后,由主要研究者、申办者和统计分析人员对数据库进行锁定。数据库锁定后抽取10%的CRF进行错误率检查。主要疗效指标错误率要求0%,其它疗效指标错误率要求0.05%以下。如果错误率要求超过该要求,将通知申办单位重新打开数据库,进行修改及寻找错误原因。数据存储于海军军医大学卫生统计学办公室的加密服务器,EDC系统设置三级权限管理(录入、审核、导出),所有数据修改需经研究者书面说明并记录审计追踪。

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

.Data Collection: This study employs a combination of electronic and paper - based recording methods. Data entry and management are undertaken by data administrators from the statistical unit, who utilize the EpiData database for these tasks. To ensure data accuracy, two data administrators independently perform double - entry and cross - check the data. Paper - based Case Report Forms (CRFs) are used to record adverse events and medical history information. Axial length is measured using the IOL - MASTER 700 instrument, and visual acuity is tested with the Standard Logarithmic Visual Acuity Chart, both operated by professional optometrists. Data Management: After confirming the accuracy of the established database, the principal investigator, sponsor, and statistical analysts will lock the database. Following database locking, 10% of the CRFs will be randomly selected for error rate inspection. The error rate for primary efficacy indicators should be 0%, and for other efficacy indicators, it should be less than 0.05%. If the error rate exceeds these requirements, the sponsor will be notified to reopen the database, make corrections, and identify the causes of the errors. The data is stored on the encrypted servers of the Office of Health Statistics at Naval Medical University. The Electronic Data Capture (EDC) system has a three - level permission management system (entry, review, export). All data modifications require a written explanation from the researcher and are recorded with an audit trail.
