Importance of conventional and emerging risk factors for stroke in different regions of the world and in different ethnic groups; a case-control study
INTERSTROKE is a large global standardised case control study to identify risk factors for stroke and estimate their relative importance. It aims to recruit over 12,000 pairs of stroke cases and matching controls from over 50 countries around the world and is expected to complete in 2014. The UK component of INTERSTROKE is supported by Chest, Heart and Stroke Scotland and The Stroke Association and aims to recruit 1,000 case-control pairs from across the UK. In addition the UK office is leading on an analysis of the variations in service delivery across the INTERSTROKE sites.
