The systematic literature search identified 623 initial records. After screening titles and abstracts against predefined exclusion criteria, 59 full-text reports were assessed for eligibility. 40 were excluded due to missing cerebellar coordinates or falling out of scope. A final total of 19 studies were included in the current meta-analysis.
