  2. Path a indicates the path from the frequency of FAFH to BMI (Mediator)
  3. Path b indicates the path from BMI to dyslipidemia
  4. Path ab indicates the indirect effect of FAFH frequency on dyslipidemia mediated by BMI
  5. Path c′ indicates the direct effect of FAFH frequency on dyslipidemia
  6. BMI body mass index, CI confidence interval, OR odds ratio
