研究目的: |
本研究采用回顾性队列设计,探讨PNI联合临床特征对妇科恶性肿瘤患者发生CIM的预测价值,识别关键危险因素,并构建验证列线图预测模型。该模型旨在实现CIM的早期预警,进而为针对高危人群开展主动干预措施提供依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
This study employed a retrospective cohort design to investigate the predictive value of the Prognostic Nutritional Index (PNI) combined with clinical characteristics for the occurrence of CIM in patients with gynecologic malignancies, to identify key risk factors, and to construct and validate a nomogram predictive model. This model aims to enable early warning of CIM, thereby providing a basis for implementing proactive interventions in high-risk populations. |

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: |
(1)数据采集与录入 ①采集方式:采用回顾性电子化数据采集,数据源为广州医科大学附属清远医院(清远市人民医院)和英德市人民医院的电子病历系统。 ②数据库建立:使用?Microsoft Excel?软件预先设计并搭建标准化的《临床资料提取表》,确保数据结构的规范性与一致性。 ③录入与质控:实行双人独立录入与交叉核对机制。如遇分歧,通过共同复核原始病历或咨询研究团队专家进行裁定,以确保数据的准确性。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
All data will be collected retrospectively from electronic medical records at two hospitals using a standardized extraction form in Microsoft Excel. A dual-entry and verification process will ensure accuracy. Data will undergo cleaning and logical checks before database locking. All patient identifiers will be removed to create an anonymized analysis dataset, which will be securely archived for study completion, publication, and audit purposes. |
