Comparing the Predictive Ability of Prognostic Models in Ischemic Stroke; Derivation, Validation, and Discrimination Beyond the ROC Curve

چکیده
A number of new studies have introduced a different risk score in contrast to National Institute of Health Stroke Scale (NIHSS) to predict prognosis in ischemic stroke (1, 2). Other recent studies have evaluated NIHSS and compared traditionally established risk scores, with newly modified models (3–8). New modeling can ease the access of scaling systems, develop a better educational background, and reveal the main common basis of the more complex models. Though the idea is clever, we’d like to highlight three educational concerns regarding the handling of the future studies on NIHSS, stroke scaling, and relative comparisons.

A predictive risk model for outcomes of ischemic stroke.
BACKGROUND AND PURPOSE The great variability of outcome seen in stroke patients has led to an interest in identifying predictors of outcome. The combination of clinical and imaging variables as predictors of stroke outcome in a multivariable risk adjustment model may be more powerful than either alone. The purpose of this study was to determine the multivariable relationship between infarct vol...
متن کاملEvaluation of IScore validity in a Greek cohort of patients with type 2 diabetes
BACKGROUND Diabetes constitutes a risk factor for stroke that also aggravates stroke prognosis. Several prognostic models have been developed for the evaluation of neurologic status, severity, short-term functional outcome and mortality of stroke patients. IScore is a novel tool recently developed in order to predict mortality rates within 30 days and 1 year after ischemic stroke and diabetes i...
متن کاملDevelopment of a new predictive model for polypathological patients. The PROFUND index.
BACKGROUND There is a concern about the accuracy of the available prognostic indexes when applying them to the emergent population of polypathological patients (PP). METHODS To develop a 1-year mortality predictive index on PP, we developed a multicenter prospective cohort-study recruiting 1.632 PP after hospital discharge, outpatient clinics, or home hospitalization, from 33 hospitals. Poten...
متن کاملThe TeleStroke Mimic (TM)‐Score: A Prediction Rule for Identifying Stroke Mimics Evaluated in a Telestroke Network
BACKGROUND Up to 30% of acute stroke evaluations are deemed stroke mimics (SM). As telestroke consultation expands across the world, increasing numbers of SM patients are likely being evaluated via Telestroke. We developed a model to prospectively identify ischemic SMs during Telestroke evaluation. METHODS AND RESULTS We analyzed 829 consecutive patients from January 2004 to April 2013 in our...
متن کاملStatistical evaluation of prognostic versus diagnostic models: beyond the ROC curve.
BACKGROUND Diagnostic and prognostic or predictive models serve different purposes. Whereas diagnostic models are usually used for classification, prognostic models incorporate the dimension of time, adding a stochastic element. CONTENT The ROC curve is typically used to evaluate clinical utility for both diagnostic and prognostic models. This curve assesses how well a test or model discrimin...
