4. Diagnostic criteria for neurological complications: cerebrovascular accident.
| Study | Neurological complication |
| Aguero‐Martinez 2012 | Neurological complication: any new‐onset psychiatric or neurological disorder with altered consciousness with or without focalization |
| Barrington 2005 | Stroke |
| Bektas 2015 | Stroke: All participants were postoperatively managed in the cardiac surgery intensive care unit. Postoperative stroke was suspected when a patient showed focal neurological deficits or delayed recovery of mental status after surgery. Such patients were referred to stroke neurologists and were evaluated by computed tomography. Post coronary artery bypass grafting, stroke was diagnosed as: 1) newly developed neurological deficits within 14 days of coronary artery bypass grafting; and 2) Low‐density lesions on postoperative computed tomography that were not observed preoperatively. Strokes that occurred within 24 hours after coronary artery bypass grafting were defined as immediate, whereas all others were considered delayed |
| Caputo 2011 | Stroke/transient ischaemic attack: diagnosis of stroke was made if evidence showed new neurological deficit with morphological substrate confirmed by computed tomography or nuclear magnetic resonance imaging |
| Celik 2015 | Stroke: neurological findings of participants (hemiparesis, hemiplegia, etc.) were followed |
| Fillinger 2002 | Neurological event: new sensorimotor neurological events |
| El‐Shora 2018 | Stroke |
| Hansdottir 2006 | Stroke: defined as a new central neurological deficit |
| Heijmans 2007 | Stroke |
| Jakobsen 2012 | Transitory Ischaemic attack lasting less than 24 hours |
| Neskovic 2013 | Stroke: new motor or sensory deficit after surgery |
| Onan 2013 | Cerebrovascular accident |
| Palomero 2008 | Focal neurological dysfunction defined as a sensory or motor deficit affecting 1 or more limbs appearing 5 days after surgery |
| Royse 2003 | Stroke |
| Scott 2001 | Cerebrovascular accident defined as a new motor or sensory deficit affecting 1 or more limbs and present on awakening from anaesthesia or occurring within the next 5 days |
| Stenseth 1996 | Hemiparesis |
| Svircevic 2011 | Stroke: a new motor or sensory deficit of central origin, persisting longer than 24 hours, preferably confirmed by computed tomography, resulting in a drop of 2 points on the Rankin scale |
| Tenenbein 2008 | Stroke or transient ischaemic attack |
| Zawar 2015 | Stroke was documented if diagnosed on computed tomography scan or magnetic resonance imaging |
