- OR, odds ratio; CI, confidence interval.
- Model 1: odds ratio by independent univariate logistic regression analysis.
- Model 2: multivariate logistic regression analysis, model 1 + sex (male or female), age (<30 years, 30-39 years, 40-49 years, 50-59 years, or ≥60 years, level of education completed (middle school or below, high school, or college or above), monthly income (<1,000,000 won, 1,000,000 – 2,000,000 won, 2,000,000 – 3,000,000 won, or ≥3,000,000 won).
- Model 3: multivariate logistic regression analysis, model 2 + smoking (non-smoker, ex-smoker or current smoker), and drinking frequency (none, ≤1 per week, ≥2 per week).
- Model 4: multivariate logistic regression analysis, model 3 + job type (white collar, service, or blue collar), company size by number of employees (<5, 5-49, 50-299, or ≥300), shift work (yes or no), and working time (<40 hours a week, 40-48 hours a week, 49-60 hours a week, or ≥61 hours a week).
