However, the effectiveness of the B4DT, particularly regarding long-term outcomes in rural clinical settings, remains underexplored.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A total of 58 patients were included using a naturalistic open-label trial design.
