Logistic model for EQ-5D dimensions of polio survivors (n = 120).

*P < 0.05;
**P < 0.001
Values are odds ratios (95% confidence intervals) after adjusting for age, education, income, region, comorbidity.
PS = polio survivor group; CG = control group; AL = activity limitation group.
Sex, male (reference), female; age, <50 years (reference), 50 ≤ age <60, ≥60 years; education, middle school or less (reference), high school or more; marital status, married (reference), other; income, lower 50% (reference), upper 50%; place of residence, city or country (reference), metropolitan area; smoking, non-smoker (reference), smoker; drinking, non-drinker (reference), drinker; comorbidity, no comorbidity (reference), comorbidity.
a Includes single, living separately, divorced, and separated by death.
b Income: monthly household income ($1 = 1020 KRW, based on the mean exchange rate at July, 2014.
Each dimension of the EQ5D scale served as a dependent variable; responses were grouped into two categories: no problem and problem.
