Likewise, meta-regression final results (see merchandise 16) shouldn't be limited to P values but should include things like impact measurements and assurance intervals,a hundred and fifty as the first example claimed higher than does in a very table. The quantity of details A part of Each and every additional analysis need to be specified if distinct from that thought of in the most crucial analyses.
