The 3\u2009L and 5\u2009L were compared in terms of distribution properties, ceiling effects, informativity, validity and discriminatory performance. Convergent validity between the 3\u2009L and 5\u2009L was tested by spearman\u2019s rank-order correlation. Discriminatory power was conducted by relative efficiency as assessed by the F statistics.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>Most participants answered to \u201cno problems\u201d on both versions of EQ-5D. The 5\u2009L trended towards a slightly lower ceiling compared with the 3\u2009L. The Shannon index improved with the 5\u2009L while the Shannon\u2019s Evenness index tended to be similar. Convergent validity was confirmed by the moderate to strong correlation for both 3\u2009L and 5\u2009L. Relative efficiency suggested that 5\u2009L had a higher absolute discriminatory power than the 3\u2009L version in terms of the presence conditions, especially for osteoporosis and metabolic syndrome.<\/jats:p>\n<\/jats:sec><jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Both the 3\u2009L and 5\u2009L are demonstrated to be valid based HRQoL instruments in Chinese elderly population. The 5\u2009L system may be preferable to the 3\u2009L, as it demonstrated superior performance with respect to lower ceiling effect and better discriminatory power. Further research is needed to examine the responsiveness of the two EQ-5D instruments in this population.<\/jats:p>\n<\/jats:sec>","DOI":"10.1186\/s12955-020-01324-0","type":"journal-article","created":{"date-parts":[[2020,4,9]],"date-time":"2020-04-09T15:03:47Z","timestamp":1586444627000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Comparing the performance of the EQ-5D-3\u2009L and the EQ-5D-5\u2009L in an elderly Chinese population"],"prefix":"10.1186","volume":"18","author":[{"given":"Ruxu","family":"You","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinyu","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhihao","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenwei","family":"Pan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qinghua","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nan","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,4,9]]},"reference":[{"issue":"3","key":"1324_CR1","doi-asserted-by":"publisher","first-page":"199","DOI":"10.1016\/0168-8510(90)90421-9","volume":"16","author":"EuroQol Group","year":"1990","unstructured":"EuroQol Group.
