how do i iterprit medeff analtsis results

[Sam Rana]

Dear Stata listers
I conducted a mediation analysis using medeff command continuous outcome continuous mediator


medeff (regress M T x) (regress Y T M x), treat(T) mediate(M) sims(1000)

Effect Mean [95% Conf. Interval]

ACME 1.115486 -.3424334 2.783301
Direct Effect 2.663043 .9861806 4.413925
Total Effect 3.778528 2.704793 4.882627
% of Tot Eff mediated .2964825 .2284646 .4124108

then ran the sensitivity analysis :

medsens (regress M T x) (regress Y T M x), treat(T) mediate(M) sims(1000)

--------------------------------------------------------------
Sensitivity results
----------------------------------------------------------------
Rho at which ACME = 0 | .3454
R^2_M*R^2_Y* at which ACME = 0: | .1193
R^2_M~R^2_Y~ at which ACME = 0: | .0075
----------------------------------------------------------------

My question is how do i interpret the results and how do I know if the mediation effect is significant?

Many thnaks.
