ADL: activities of daily living; MN+/SA+: malnutrition combined with sarcopenia; MN+/SA−: malnutrition without sarcopenia; MN−/SA+: normal nutrition with sarcopenia; MN−/SA−: normal nutrition without sarcopenia; N/A: not included in the models.
aOnly significant variables are presented except for age and gender.
bMalnutrition and sarcopenia were treated as independent variables.
cMalnutrition combined with sarcopenia was treated as one variable.
