Note: Outcome and mediator variables were standardised. The total effect consists of four components: CDE, PIE, INTref and INTmed. Differential exposure is defined as the sum of the components PIE and INTmed; differential impact/susceptibility is defined as the sum of the components INTref and INTmed.
CDE, controlled direct effect; INTmed, mediated interaction; INTref, reference interaction; PIE, pure indirect effect.
