Investigation of second to fourth finger length ratio (2D:4D) in patients with bipolar disorder.

CONCLUSION: These findings suggest that a high 2D:4D digit ratio of right hand is associated with the presence of bipolar disorder in males. Further large-scale, prospective studies are needed to explain the validity of this marker and its relationship with bipolar disorder. PMID: 32555980 [PubMed - as supplied by publisher]
