Berberine is a promising candidate for future antidepressant therapies; however, no comprehensive systematic evaluation has been conducted to date.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Five electronic databases\u2014PubMed, Embase, Web of Science, OVID, and the Cochrane Library\u2014were systematically searched to identify preclinical studies investigating the antidepressant effects of berberine. Outcomes were assessed using the standardized mean difference with 95% confidence intervals to evaluate overall effect sizes. Study quality was evaluated using the 10-item Systematic Review Centre for Laboratory Animal Experimentation risk of bias tool. Publication bias was assessed if more than 10 studies were included in an analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 20 preclinical studies evaluating berberine\u2018s antidepressant effects were identified.
