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.
