  • PMx: particulate matter with an aerodynamic cross section of x µm; FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity; M0: crude model estimated on 520 patients (1833 measurements); M1: model adjusted on recipient age (continuous), sex, smoking status of both donor and recipient, body mass index (continuous), donor age, type of lung transplant, underlying disease, sex mismatch, anti-human leukocyte antigen antibodies, transplant centre, living area and, for the 6-month, 3-month and 1-month exposure, on temperature and humidity, estimated on 495 patients (1770 measurements); M2: M1 model further adjusted on treated Pseudomonas infection, cytomegalovirus treated disease, immunosuppression induction and acute rejection treated episodes, estimated on 487 patients (1751 measurements).
