Day\u2010patient treatment offers a middle ground by providing intensive daytime therapy with the opportunity to apply skills at home. This meta\u2010analysis evaluated the effectiveness of day\u2010patient treatment for BN and explored potential outcome moderators.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A systematic search yielded 1664 records, and 20 studies were included in the analysis.
