We used odds ratios (OR) and their 95% confidence intervals (CI) to assess the association between the ability to open a PET bottle cap and LS, frailty and sarcopenia, as well as the screening ability of this method. LS was evaluated using the stand\u2010up and two\u2010step tests and Geriatric Locomotive Function Scale\u20105; frailty was evaluated using the Japanese version of the Cardiovascular Health Study criteria; and sarcopenia was evaluated using grip strength, walking speed and skeletal muscle mass index.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>After adjusting for age, sex and body mass index, the binary logistic regression analysis showed that the inability to open a PET bottle cap was associated with LS stages 2 and 3 (OR 2.72, 95% CI 1.46\u20135.07), frailty according to the Japanese version of the Cardiovascular Health Study criteria (OR 3.38, 95% CI 1.23\u20139.24) and sarcopenia (OR 3.61, 95% CI 1.67\u20137.79).
