缺血性卒中患者院内复发风险预测模型开发与验证研究 Development and Validation of a Predictive Model for In-Hospital Recurrence Risk in Ischemic Stroke Patients
目的 开发基于机器学习算法的缺血性卒中患者院内复发风险的预测模型,并进行外部验证,为相关研究提供借鉴。 方法 开发队列为中国卒中联盟(China Stroke Center Alliance,CSCA)研究队列,将此队列中的缺血性卒中患者按照8∶2随机划分为训练集和内部验证集。验证队列为第3次中国国家卒中登记(the third China national stroke registry,CNSR-Ⅲ)研究队列。基于指南、文献回顾,确定备选预测因子,然后采用拉索(least absolute shrinkage and selection operator,LASSO)回归进行筛选。基于l...
