Flowchart of literature search and identification of eligible articles. The initial database search resulted in 113 records from PubMed and 423 records from Google Scholar, together which resulted in 412 records after the exclusion of duplicates. The first screening of titles and abstracts excluded 306 records for the following reasons: 133 records were not an original research paper, 157 records did not target bipolar disorder, 9 records did not include MRI data, and 7 records were not in English. A second screening of the 106 full‐text articles led to the exclusion of 61 records as a result of the following: 39 records did not use a network‐based approach, 8 records were based on pediatric or relatives of bipolar disorder, and 14 records evaluated structural brain networks. An additional four records were also included from cross‐referencing, resulting in a total of 49 records for this review. MRI, magnetic resonance imaging.
