Randomised, single blind (blinded assessment of spirometry results), controlled trial with follow up at 12 months.

140 consecutive patients (mean age 49 y, 61% women) with bronchial asthma or COPD who were 18–70 years of age and did not have unstable ischaemic heart disease, heart failure, serious hypertension, diabetes mellitus, or kidney or liver failure. Patients with asthma had to have ≥80% of predicted forced expiratory volume at 1 second (FEV1) in stable phase and 1 of a positive reversibility test, documented 20% spontaneous variability (peak expiratory flow and FEV1), or a positive metacholine test. Patients with COPD had to have ≥40% and <80% of predicted FEV1. Follow up was …
