How Strong the Predictive Ability of the Variable Age and Stroke Severity for Patients Presented Late

How Strong the Predictive Ability of the Variable Age and Stroke Severity for Patients Presented Late, Background and purpose: Age and stroke severity as 2 independent predictors have been included in many well-known prediction models. However, whether the model consisting of the 2 variables derived from early arrival group could bring equal clinical benefit for those patients presented late was unclear. This study aimed to investigate the performance of this transformation., Background and purpose: Age and stroke severity as 2 independent predictors have been included in many well-known prediction models. However, whether the model consisting of the 2 variables derived from early arrival group could bring equal clinical benefit for those patients presented late was unclear. This study aimed to investigate the performance of this transformation. Methods: We enrolled ischemic stroke patients admitted to our stroke center within 3 days after symptom onset from January 1, 2018 to March 31, 2019.These patients were divided into 2 groups, early arrival group within 6 hours after onset and late arrival group between 6 hours and 3 days., admin,
