  1. Model 1: Odds ratio by independent univariate logistic regression analysis
  2. Model 2: Multivariate logistic regression analysis, model 1 + age, level of education completed (middle school or below, high school, or college or above), marital status (married, divorced, or widowed), smoking (non-smoker, ex-smoker, or current smoker), and drinking frequency (none, ≤1 per week, ≥2 per week)
  3. Model 3: Multivariate logistic regression analysis, model 2 + service area for patrol (rural or urban), duration of patrol service (<10 years, 10–19 years, or ≥20 years), and job stress
  4. Model 4: Multivariate logistic regression analysis, model 3 + depression (normal, mild, severe, or very severe)
  5. Abbreviations: OR odds ratio, CI confidence interval
  6. aCategorical data 1: Data comparing two groups (64.5 was a standard value)
  7. bContinuous data 2: Continuous comparison of data based on the total scores of K-CDRI; a higher score means higher resilience
