How to check whether significancy of posterior estimates

Hi, is there any ways to check whether estimated parameters (in my case, Bayesian DSGE estimation) are statistically significant?
According to dynare output, we can see t-statistics. I am not sure whether I just check them or not.
Also, I am confused of how they are computed given that we assume that each parameter follows distribution that is different from each other.
