The observed agreement between the two readings was 93 per cent, and after adjusting for the expected chance agreement a kappa value of 0.73 was obtained. At the first reading 4 ulcers, and at the second reading 8 ulcers were interpreted as malignant. None of these interpretations agreed. In a questionnaire study it was demonstrated that gastroenterologists had a realistic impression of the level of agreement in the radiographic detection of gastric ulcer.<\/jats:p>","DOI":"10.1177\/028418518502600311","type":"journal-article","created":{"date-parts":[[2015,6,11]],"date-time":"2015-06-11T06:25:56Z","timestamp":1434003956000},"page":"289-292","source":"Crossref","is-referenced-by-count":4,"title":["Interobserver Variation in the Radiographic Diagnosis of Gastric Ulcer"],"prefix":"10.1177","volume":"26","author":[{"given":"T.","family":"Gj\u00f8rup","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Nielsen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.
