* p < 0.1, ** p < 0.05, *** p < 0.01; ACME is the average causal mediation effect, ADE is the average direct effect, and total effect = ADE + ACME;
is the value when ACEM = 0;
and
represent the proportions of residual variance in the mediation model and outcome model as explained solely by unobserved confounders, respectively;
is the value when ACEM = 0;
and
represent the coefficients of determination of the mediation model and the outcome model, respectively
