Effect of Preoperative Respiratory Training on Perioperative Outcomes in Thoracic Surgery: A Systematic Review and Meta-Analysis

Its impact on spirometry-based pulmonary function and length of hospital stay remains uncertain. Further large-scale trials are needed to investigate the effect of integrating perioperative care into routine healthcare, especially for high-risk patients.
