Data are expressed as odds ratio (OR) and 95% confidential interval (CI) of logistic regression analysis.

^aOdds ratio shows relation with each domain of WHOQOL-BREF and each factor after adjusting for sex, age, and ADL.

^bOdds ratio shows relation with each domain and the factors that tend to be related (P < 0.10) when adjusting for sex, age, and ADL.

P value by multiple logistic regression analysis.
