  1. Qb describes the variation in effect sizes that can be ascribed to differences between categories. Qt assesses whether the effect sizes are homogeneous. Bold letters indicate significant values
  2. (–) These analysis were not carried out because some of the studies that evaluated bacterial biomass and FLF biomass were carried out under greenhouse conditions
