Pooled effect-size estimates, heterogeneity and publication bias for the animal studies by sub-group meta-analyses indicated in the row.

A Effect-size estimates were of a larger magnitude in studies that measured central- as compared to serum BDNF (all P-values P-values P-values > .5).B Chronic ECS yielded larger effect-size estimates as compared to single ECS (P C Studies that sampled BDNF mRNA yielded larger effect-size estimates as compared to studies that sampled BDNF protein (P D Among the studies that are characterized as measuring BDNF mRNA were 3 effect-sizes on BDNF RNA and 9 on the precursor protein pro-BDNF. Excluding these effect-sizes did not change the results.* Statistical significant at P ** Statistical significance at P *** Statistical significance at P Pooled effect-size estimates, heterogeneity and publication bias for the animal studies by sub-group meta-analyses indicated in the row.
