Note. Model 1: multiple linear regression analysis between sarcopenia and number of teeth; Model 2: multiple linear regression analysis between sarcopenia and number of teeth adjusted by MNA-SF score; Model 3: multiple linear regression analysis between MNA-SF score and number of teeth; All the models were adjusted by false teeth status, gender, age, ethnic group, life styles (smoking), educational, living alone status, marriage status, chronic diseases status, depression, sleep disorders and cognitive status
