Using the predefined study criteria, there were 191 definite strokes (76%), 20 probable strokes (8%), 11 possible strokes and 11 cases of transient ischaemic attacks (4% each) i.e. 233\/250 (93%) with possible or definite stroke or transient ischaemic attacks. Stroke could not be verified using hospital records in 13 cases (5%) and 4 cases (2%) had other diagnoses: 3 cases of vascular dementia and 1 case of benign intracranial hypertension. The diagnosis of stroke in 185 out of 250 cases identified in the EPIC-Norfolk (74.0%) was supported by radiological evidence using WHO criteria.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Death certificates and hospital record linkage in this British prospective study have a high accuracy or positive predictive value in correctly identifying incident stroke cases.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1471-2288-8-74","type":"journal-article","created":{"date-parts":[[2008,11,11]],"date-time":"2008-11-11T07:14:00Z","timestamp":1226387640000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["Accuracy of death certification and hospital record linkage for identification of incident stroke"],"prefix":"10.1186","volume":"8","author":[{"given":"Shubhada","family":"Sinha","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Phyo K","family":"Myint","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert N","family":"Luben","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kay-Tee","family":"Khaw","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2008,11,10]]},"reference":[{"key":"310_CR1","doi-asserted-by":"publisher","first-page":"1334","DOI":"10.1161\/01.STR.26.8.1334","volume":"26","author":"PG O'Mahony","year":"1995","unstructured":"O'Mahony PG, Dobson R, Rodgers H, James OF, Thomson RG: Validation of a population screening questionnaire to assess prevalence of stroke.
