Data are presented as mean±sd or n (%) unless otherwise stated. A two-sample t-test was used for normally distributed variables and Pearson's Chi-squared test for categorical variables. MPR: medication possession ratio; BMI: body mass index; FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity; HbA1c: haemoglobin A1c; i.v.: intravenous.
