The AUCs of modified-Krishnan\u2019s FI (AUC = 0.856; 95% confidence interval (CI) = 0.767\u20130.945) and the CSHA-FI (AUC = 0.793; 95% CI = 0.652\u20130.934) were used to compare the effectiveness in predicting patient mortality. The optimal predictive scores were 0.335 and 0.28, respectively. The Pearson correlation analysis showed that the modified-Krishnan\u2019s FI correlated with the Japanese Orthopaedic Association hip score (pain, activity, walking ability, and ability for daily living; R = \u22120.249, p = 0.005), while the CSHA-FI was not correlated ( R = \u22120.125, p = 0.170). The modified-Krishnan\u2019s FI ( R = \u22120.415, p &lt; 0.001) and the CSHA-FI ( R = \u22120.332, p &lt; 0.001) were both significantly correlated with the functional recovery scale score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The modified-Krishnan\u2019s FI and the CSHA-FI were effective in the prediction of postoperative mortality. But the modified-Krishnan\u2019s FI was more consistently associated with the recovery of hip function and daily activities at 3 months after the operation than that of the CSHA-FI. The modified-Krishnan\u2019s FI was more suitable to utilize for risk stratification, identifying deficits, and predicting recovery capacity in hip fracture patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/2309499020901891","type":"journal-article","created":{"date-parts":[[2020,2,7]],"date-time":"2020-02-07T09:21:51Z","timestamp":1581067311000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Comparison of two frailty indexes in hip fractures"],"prefix":"10.1177","volume":"28","author":[{"given":"Weiyan","family":"Lu","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Trauma, Foot and Ankle Surgery, The First Affiliated Hospital of Fujian Medical University, Fuzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liqun","family":"Dai","sequence":"additional","affiliation":[{"name":"Department of Musculoskeletal Tumor, Joint Surgery and Sports Medicine, The First Affiliated Hospital of Fujian Medical University, Fuzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0953-5488","authenticated-orcid":false,"given":"Gui","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Trauma, Foot and Ankle Surgery, The First Affiliated Hospital of Fujian Medical University, Fuzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8423-6800","authenticated-orcid":false,"given":"Rong","family":"Hu","sequence":"additional","affiliation":[{"name":"Department of Adult Nursing, School of Nursing, Fujian Medical University, Fuzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,2,7]]},"reference":[{"key":"bibr1-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1007\/s12603-016-0830-y"},{"key":"bibr2-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2018.10.008"},{"key":"bibr3-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(12)62167-9"},{"key":"bibr4-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/aft084"},{"key":"bibr5-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-013-3334-7"},{"key":"bibr6-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1177\/2151458515591170"},{"key":"bibr7-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1007\/s00268-018-4734-3"},{"key":"bibr8-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1111\/jgs.14387"},{"key":"bibr9-2309499020901891","doi-asserted-by":"publisher","DOI":"10.4103\/aer.AER_61_18"},{"key":"bibr10-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afr179"},{"key":"bibr11-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afr182"},{"key":"bibr12-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1503\/cmaj.050051"},{"key":"bibr13-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1097\/BOT.0000000000001140"},{"key":"bibr14-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2318-8-24"},{"key":"bibr15-2309499020901891","first-page":"864","volume":"69","author":"Imura S","year":"1995","journal-title":"J Jpn Orthop Assoc"},{"key":"bibr16-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1007\/s00776-006-1073-2"},{"key":"bibr17-2309499020901891","doi-asserted-by":"publisher","DOI":"10.1097\/00005131-200001000-00005"},{"key":"bibr18-2309499020901891","volume-title":"Application of SPSS (PASW) 17.0 in medical statistics","author":"BR.
