However, hardly any data exist on longer term follow-up, especially on quality of life. Our aim was to investigate long-term follow-up after EBV treatment up to 3\u2005years including quality of life in a real-life routine clinical setting.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively included patients who underwent EBV treatment in our hospital in the Netherlands at least 3\u2005years prior. Patients were invited for annual visits to our hospital, and spirometry, body plethysmography, 6-min walk distance (6MWD) test and St George's Respiratory Questionnaire (SGRQ) were performed during these visits.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At 1-, 2- and 3-year follow-up, data were available from 189, 146 and 112 patients, respectively. Forced expiratory volume in 1\u2005s, residual volume and SGRQ total score significantly improved up to 3\u2005years after treatment compared with baseline, and 6MWD up to 2\u2005years after treatment. In general, the magnitude of improvements gradually decreased over time.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our results show that patients can benefit at least up to 3\u2005years after EBV treatment.
