You should take the dependency of correlations computed based on the same sample into consideration. In other words, if you have cor(x1,z) and cor(x2,z) based on the same sample of subjects, then these two correlations are not independent. Note that rma.mv() with random effects is not sufficient to account for this. The covariance between the two correlations should go into the V matrix. See help(rcalc).
