  3. *Presented for significant differences between “job strain-ratio >1” and “job strain-ratio ≤1”. T-test was used for continuous variables and chi2 for categorical variables
  4. **Fisher’s exact test was used since the number of underweight subjects in the different categories were less than 5, rendering the chi2-test potentially invalid
