Inconsistent centralised versus non-centralised ischaemic stroke aetiology

Abstract: Background and purposeThe Trial of Org 10 172 in Acute Stroke Treatment (TOAST) system is the most widely used aetiological categorisation system in clinical practice and research. Limited studies have validated the accuracy of routine aetiological diagnosis of patients with ischaemic stroke according to the TOAST criteria when the reported subtype is assumed to be correct. We investigated the agreement between centralised and non-centralised (site-reported, at discharge) stroke subtypes in the Third China Nat… Show more

“… 21 Neurologists and radiologists evaluated each centralised stroke subtype based on a previously established standardised element. 22 Two experts interpreted each case and recorded it on a standardised report form in the EDC system. They remained blind to one another’s input data during interpretation.…”

“…Trained research coordinators at each site collected information of age, prestroke modified Rankin Scale (mRS) score and National Institutes of Health Stroke Scale (NIHSS) score through a direct interview at admission, and baseline data from medical records, including sex, body mass index (BMI, the weight in kilograms divided by the square of the height in meters), cigarette smoking, medical history of hypertension, diabetes, hypercholesterolemia, ischemic stroke and coronary heart disease, and laboratory test of leukocyte counts. The TOAST (Trial of ORG 10,172 in Acute Stroke Treatment) criteria were used for centralized etiology classification of ischemic stroke [ 19 , 20 ].…”

“…14 The North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria was adopted to adjust the assessment of sECAS. 15,16 The brain tissue damage caused by the acute ischaemic stroke, measured as the volume of the ischaemic lesions, was calculated from the diffusion-weighted image (DWI) and apparent diffusion coefficient (ADC) scans using a deep learning segmentation model. 17…”
