Supplementary Material for: Population-Based Validation of the iScore for Predicting Mortality and Early Functional Outcome in Ischemic Stroke Patients

Background: We aimed to determine the accuracy of the iScore for predicting mortality and early disability following ischemic stroke in a French population-based study. Methods: All patients with acute ischemic stroke were identified among residents of the city of Dijon, France, between 2006 and 2011, using a population-based stroke registry. The 30-day iScore and 1-year iScore were calculated. A logistic regression model was used to assess the performance of the iScore for predicting both 30-day and 1-year mortality, and poor functional outcome at discharge (modified Rankin Scale score of 3-6). The discrimination and calibration of the model were assessed using the c-statistic and the Hosm…
