Objectives of Study: |
(1) Primary Research Objectives 1. To systematically evaluate the application value of imaging parameters such as MRI-based vertebral bone quality score (VBQ) and vertebral fat fraction (PDFF) in the assessment of bone density in renal transplant patients, using DXA and QCT bone density results as the reference standard; 2. To dynamically assess the monitoring effectiveness of DXA, QCT, and related MRI indicators for changes in bone density in renal transplant patients through multi-timepoint follow-up. (2) Secondary Research Objectives 1. To analyze the correlation between bone density and blood metabolic parameters such as bone metabolism indicators and lipid metabolism indicators in renal transplant patients; 2. To explore the changes in imaging parameters such as vertebral bone quality, bone marrow fat content, and back muscle composition at different follow-up time points; 3. To investigate the potential value of different imaging parameters in predicting the risk of bone loss or osteoporosis, providing a basis for the establishment of subsequent risk stratification and predictive models. |

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: |
本研究的数据采集与管理包括病例报告表(Case Report Form, CRF)和电子数据采集系统(Electronic Data Capture, EDC)两部分。 1. 病例报告表(CRF) 本研究设计统一的标准化病例报告表(CRF),用于系统收集受试者的相关信息,包括: (1)人口学资料(年龄、性别、身高、体重等); (2)临床资料(肾移植时间、基础疾病、用药情况等); (3)实验室检测指标(骨代谢指标、脂代谢指标等); (4)影像学检查数据(DXA、QCT、CACS及MRI相关参数,包括BMD、VBQ、PDFF等)。 所有数据由经过培训的研究人员按照统一标准进行填写,确保数据完整性与一致性。 2. 电子数据采集系统(EDC) 本研究采用基于互联网的电子数据采集与管理系统(EDC,如ResMan系统或医院科研数据库平台)进行数据录入与管理。所有CRF数据由两名研究人员分别独立录入,并进行逻辑核查与一致性校对,以降低录入错误风险。 3. 数据质量控制 为保证数据质量,本研究将采取以下措施: (1)建立数据管理标准操作流程(SOP),对数据采集、录入、核查及锁库进行规范; (2)定期开展数据核查与质控,发现问题及时更正并记录; (3)对关键变量(如BMD、VBQ、PDFF等)进行重点核查; (4)影像数据由至少两名影像医师在盲法条件下独立测量,并评估一致性(ICC)。 4. 数据安全与保密 所有受试者数据均采用唯一编码进行匿名化处理,个人身份信息与研究数据分开存储。电子数据存储于加密数据库中,仅限研究团队授权成员访问。研究过程中严格遵守相关法律法规及医院数据安全管理规定,确保受试者隐私不被泄露。 5. 数据锁定与保存 在研究结束后,完成数据清理与核查后进行数据库锁定(database lock)。所有研究数据将按照医院相关规定保存至少5年,之后按规范统一处理。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
The data collection and management in this study include two parts: Case Report Forms (CRF) and Electronic Data Capture systems (EDC). 1. Case Report Form (CRF) This study designed a standardized CRF to systematically collect relevant information about participants, including: (1) Demographic data (age, gender, height, weight, etc.); (2) Clinical data (date of kidney transplantation, underlying diseases, medication status, etc.); (3) Laboratory test indicators (bone metabolism indicators, lipid metabolism indicators, etc.); (4) Imaging data (parameters related to DXA, QCT, CACS, and MRI, including BMD, VBQ, PDFF, etc.). All data were filled out by trained researchers following a unified standard to ensure data completeness and consistency. 2. Electronic Data Capture (EDC) This study used an internet-based electronic data capture and management system (EDC, such as ResMan system or hospital research database platform) for data entry and management. All CRF data were independently entered by two researchers and underwent logical checks and consistency review to reduce the risk of entry errors. 3. Data Quality Control To ensure data quality, the following measures will be taken in this study: (1) Establish a standard operating procedure (SOP) for data management to standardize data collection, entry, verification, and database locking; (2) Conduct regular data verification and quality control, promptly correct any issues found, and record them; (3) Perform focused verification on key variables (such as BMD, VBQ, PDFF, etc.); (4) Imaging data were independently measured by at least two radiologists under blinded conditions, and the consistency (ICC) was evaluated. 4. Data Security and Confidentiality All participant data were anonymized using unique codes, and personal identity information was stored separately from research data. Electronic data were stored in an encrypted database and only accessible to authorized members of the research team. During the study, relevant laws and regulations as well as hospital data security management policies were strictly followed to ensure that participants' privacy is not compromised. 5. Data Locking and Storage After the study, the database will be locked (database lock) following data cleaning and verification. All research data will be stored according to hospital regulations for at least 5 years, and then uniformly processed according to established guidelines. |
