Please report the main results of the meta-analysis in the abstract (effect size and p-value).
No conclusion was included in the abstract. Besides, the background of the research was too long in the abstract. The motivation and objective of the study should be clearly stated in the abstract.

It is not clear whether internet gambling disorder is also included in the review.
Please cite relevant reviews on the topic of NIBS on substance addiction and gambling disorders.
The neural mechanism of NIBS in revising gambling-related brain pathology should be added.
