  1. Notes: Timing is referred to the rTMS intervention; recovery: recovery of the phenotype in animal models of disease.
  2. SPT sucrose preference test, SCT sucrose consumption test, ↑: statistically significant change, ns not significant.
  3. aIn all studies except this one at least 1 assessment was performed shortly after the end of the rTMS intervention; as in this study by assessments were only performed during rTMS intervention, the one closest to the end of the intervention was selected for the inclusion in the meta-analysis. bNot included in the meta-analysis.
