Ischemic stroke was defined as either of : 1) Rapid onset (or present on awakening) of a new focal neurological deficit with clinical (>24 hours symptoms/signs) or imaging evidence of infarction that was not attributable to a non-ischemic cause; 2) Acute worsening of an existing focal neurological deficit that was judged to be attributable to a new infarction or extension of the previous infarction in the same vascular territory, based on persisting symptoms/signs or imaging evidence of infarction and no evidence of a non-ischemic etiology. If imaging was inconclusive, persistent symptoms/signs must be significant (worsening of NIHSS score of 4 or more) and sustained (duration of ≥24 hours or until death). Covert brain infarcts were defined as incident infarcts detected by serial MRI in the absence of an adjudicated stroke consistent with the location of the infarct. MRI criteria for brain infarction were available in the MRI procedures manual.

FAS

CV death included death due to stroke, MI, heart failure or cardiogenic shock, sudden death or any other death due to other cardiovascular causes. Death due to non-traumatic hemorrhage was included. Acute MI was used when there was evidence of myocardial necrosis in a clinical setting consistent with acute myocardial ischemia. According to MI Universal Definition from 2018 the diagnosis of MI required the combination of: 1) Presence of acute myocardial injury, and 2) Evidence of acute myocardial ischemia derived from the clinical presentation, electrocardiographic changes, or the results of myocardial or coronary artery imaging, or in case of post-mortem pathological findings irrespective of biomarker values. Systemic embolism was defined as abrupt vascular insufficiency associated with clinical or radiological evidence of arterial occlusion in the absence of other likely mechanisms (this did not include thromboembolism of the pulmonary vasculature or venous thrombosis).

FAS

Definition of symptomatic ischemic stroke can be referred to first Primary endpoint.

FAS

Definition of covert brain infarcts can be referred to first Primary endpoint.

FAS

Definition of symptomatic ischemic stroke can be referred to first Primary endpoint. Definition of CV death and MI can be referred to first Second endpoint.

FAS

Definition of symptomatic ischemic can be referred to fourth secondary endpoint. Hemorrhagic stroke was defined as an acute, atraumatic extravasation of blood into the brain parenchyma, intraventricular or subarachnoid space with associated neurological symptoms. This did not include microbleeds or hemorrhagic transformation of an ischemic stroke.

FAS

Modified ranking score (mRS): 0-No symptoms at all; 1-No significant disability despite symptoms; despite symptoms, able to carry out all usual duties and activities; 2-Slight disability; unable to carry out all previous activities but able to look after own affairs without assistance; 3-Moderate disability; requiring some help, but able to walk without assistance; 4-Moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance; 5-Severe disability; bedridden, incontinent and requiring constant nursing care and attention; 6-Death.

ISTH Major Bleeding criteria: 1. Fatal bleeding, and/or 2. Symptomatic bleeding in a critical area or organ (intracranial, intraocular, intraspinal, pericardial, retroperitoneal, intraarticular, or intramuscular with compartment syndrome), and/or 3. Clinically overt bleeding associated with a recent decrease in the hemoglobin level of ≥ 2 g/dL (20 g/L; 1.24 mmol/L) compared to the most recent hemoglobin value available before the event, and/or 4. Clinically overt bleeding leading to transfusion of 2 or more units of packed red blood cells or whole blood. ISTH Clinically Relevant Non-Major Bleeding is considered any sign or symptom of hemorrhage that does not fit the criteria for the ISTH definition of major bleeding, but does meet at least one of the following criteria 1. requiring medical intervention by a healthcare professional. 2. leading to hospitalization or increased level of care. 3. prompting a face to face (i.e. not just a telephone or electronic communication) evaluation.

SAF

All bleeding events occurred from first intake of study intervention until 2 days after the last intake of study intervention.

SAF

Definition of ISTH major bleeding can be referred to second Primary endpoint.

SAF

Definition of ISTH CRNM bleeding can be referred to second Primary endpoint.

SAF

All other overt bleeding episodes not meeting the above criteria for ISTH major or CRNM bleeding were classified as minor bleeding (e.g. bleeding from a minor wound that does not prompt a face-to-face evaluation for a physical examination or laboratory testing).

SAF

Non-traumatic intracerebral hemorrhage was defined as a hemorrhagic stroke on the "recurrent stroke" CRF page that is in addition classified as a bleeding with bleeding site intracranial (-subarachnoid, -intraparenchymal [excluding microbleeds], or -intraventricular) and spontaneous causality of bleeding, excluding all symptomatic and hemorrhagic transformation (defined by the PT "hemorrhagic transformation").
