例数:

Sample size:

100

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Vulnerable plaques were defined as those exhibiting intraplaque hemorrhage, ulceration, or a lipid-rich necrotic core occupying ≥40% of the plaque area.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

稳定斑块:HR-MRI分析不含有上述易损标准的斑块。

例数:

Sample size:

0

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

Stable plaques were defined as those without any of the aforementioned vulnerable features.

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:

本研究是一项由研究者发起的、预算有限的研究。因此,数据采集与管理将采用以纸质病例报告表(CRF)为核心的严谨流程,并辅以多重质量控制步骤以确保数据的可靠性。具体流程如下: 1. 数据采集:所有研究数据将使用预先设计的标准化病例报告表(CRF)在研究中心进行收集。CRF设计清晰,包含必要的逻辑核查点,以指导研究者准确填写。 2. 数据转录与验证:所有CRF数据将由授权的研究人员转录至受密码保护的电子数据库(Microsoft Excel);为确保转录的准确性,我们将采用独立双次录入的方式进行。即由两名不同的数据录入员分别将同一份CRF数据录入数据库,随后由系统或第三方进行比对,任何不一致之处将返回原始CRF进行核对与修正。 3. 质量控制:研究监查员将定期对录入电子数据库的数据与患者病历中的源文件进行核对,确保数据与原始记录一致。数据管理员将定期对电子数据集进行人工审查,以识别在范围、逻辑或一致性上存在疑义的数据(例如,相互矛盾的斑块特征和易损性),并通过生成数据质疑表的方式要求研究中心澄清;电子数据库的访问权限将被严格限制。任何对已录入数据的修正都必须有书面记录,并需经主要研究者或其授权人批准。所有数据变更将在电子数据库中保留修改记录(使用Excel的“跟踪更改”功能)。 4. 数据锁定与归档:在研究结束时,在所有数据清理和核查工作完成后,最终的数据集将被锁定并归档。所有纸质CRF和源文件将根据伦理委员会的要求在研究中心安全保存至少5年。

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

As an investigator-initiated trial with limited funding, this study will employ a rigorous, paper-based data collection process supplemented by multiple quality control measures to ensure data integrity in lieu of a professional Electronic Data Capture (EDC) system. 1. Data Collection: All study data will be collected at the investigational sites using pre-designed, standardized Case Report Forms (CRFs). The CRFs are clearly structured and include necessary logic checkpoints to guide investigators in accurate completion. 2. Data Transcription and Validation: All CRF data will be transcribed by authorized research personnel into a password-protected electronic database (Microsoft Excel). To ensure transcription accuracy, an independent double-data entry procedure will be implemented. This involves two different data entry clerks independently transcribing the same set of CRF data into the database. The entries are subsequently compared, either systematically or by a third party, and any discrepancies are resolved by verification against the original CRF. 3. Quality Control: Study monitors will periodically perform source data verification (SDV), cross-checking the data in the electronic database against the original source documents in the patient medical records to ensure consistency. The data manager will conduct regular manual reviews of the electronic dataset to identify potential issues regarding range, logic, or consistency (e.g., contradictory plaque characteristics and vulnerability classifications). Data queries will be generated and sent to the investigational sites for clarification. Access to the electronic database will be strictly restricted. Any corrections to entered data must be formally documented and require approval from the Principal Investigator or an authorized delegate. A record of all data changes will be maintained within the electronic database using the "Track Changes" feature in Excel. 4. Database Lock and Archiving: Upon study completion, after all data cleaning and verification activities are finalized, the final dataset will be locked and archived. All paper CRFs and source documents will be securely stored at the investigational sites for a minimum of 5 years, in accordance with the requirements of the Ethics Committee.
