预测卒中后转归的多变量模型可作为评估治疗组是否平衡的标准 ,还能预测失访者的预后。我们通过对来自TiriazadMesylate的急性卒中患者作随机化试验 (RANTTAS) ,得出了一系列预测风险的模型并通过了内部资料的有效性检验 ,然而这个模型尚缺乏外部资料的检验。本研究的目的是评?
Multivariable models for predicting post-stroke outcome can be used as a criterion for assessing the balance of the treatment group and for predicting the prognosis of those lost. We conducted a randomized trial (RANTTAS) of acute stroke patients from Tiriazad Mesylate to arrive at a series of models for predicting risk and passed the validation of the internal data. However, this model lacks the test of external data. The purpose of this study is to evaluate
