The sensitivity increased and the specificity decreased using a lower probability threshold for redisplacement. The area under the receiver operating characteristic curve of the EWC was poor the Mackenney's thresholds [0.47; 95% confidence interval (CI): 0.36\u20130.59] and adequate for the Dutch thresholds (0.71; 95% CI: 0.58\u20130.84).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions:<\/jats:title>\n            <jats:p>The EWC was a poor predictor of fracture redisplacement greater than threshold in displaced distal radius fractures in our patient population.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1097\/bot.0000000000001105","type":"journal-article","created":{"date-parts":[[2018,1,10]],"date-time":"2018-01-10T07:03:26Z","timestamp":1515567806000},"page":"e92-e96","source":"Crossref","is-referenced-by-count":19,"title":["Prediction of Distal Radius Fracture Redisplacement: A Validation Study"],"prefix":"10.1097","volume":"32","author":[{"given":"Monique M.
