...5 .

Does this mean that, overall, there is a significant effect of "group" on
the overall effect size (based on the QM test)? If I want to test whether
the effect size for plants is different to that for animals, can I use:
MixModel2<-rma(z, v.z., mods=cbind(k.plant), data=MData,
subset=(Response=="Tolerance")) ?
Here I get:
Test of Moderators (coefficient(s) 2):
QM(df = 1) = 0.0039, p-val = 0.9502
