研究目的:

本研究旨在通过构建多模型堆叠集成模型,结合传统临床变量和机器学习技术,预测克罗恩病患者的手术风险、术后血栓风险及生物制剂治疗效果。通过比较不同模型的性能,我们希望为临床提供精准的预测支持,帮助优化个体化治疗方案,尤其在决定是否使用生物制剂时提供数据依据,从而改善患者的治疗效果和预后。  

Objectives of Study:

This study aims to develop a multi-model stacked ensemble model that integrates traditional clinical variables with machine learning techniques to predict surgical risk, postoperative thrombotic risk, and the efficacy of biologic therapy in patients with Crohn’s disease. By comparing the performance of different models, we hope to provide precise predictive support for clinical decision-making, helping to optimize personalized treatment strategies—particularly offering data-driven guidance on the use of biologic agents—thereby improving patient outcomes and prognosis.

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

Due to the sensitive nature of the patient data involved in this study, and to ensure strict protection of patient privacy and data security, individual participant data (IPD) will not be shared with other researchers. The confidentiality of participants is of utmost importance, and all data will be handled in accordance with applicable ethical guidelines and data protection regulations. Therefore, no plans are in place for external data sharing.

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:

录入采用相应的数据库系统双人双机录入,之后对数据库进行两遍比对, 利用自动 化校验工具对比两份数据,对不一致项进行溯源核查,误差率控制在 0.5% 以内,期间 若发现问题及时通知研究者,要求研究者做出回答。他们之间的各种疑问及解答的交换 应当采用疑问表形式,疑问表应保存备查。所有资料经 Epidata3.0 软件建立数据库,采 用统一标准录入研究对象临床资料。

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

Data entry was performed using a double-entry, double-computer system into the corresponding database. Subsequently, the database was cross-checked twice, and automated verification tools were used to compare the two datasets. Any discrepancies were traced and verified, maintaining an error rate below 0.5%. If issues were identified during this process, researchers were promptly notified and required to provide explanations. All queries and responses between the parties were documented in query forms, which were retained for reference. The entire dataset was managed using Epidata 3.0 software, with clinical data of study subjects entered according to unified standards.
