Does describing to patients how smoking has accelerated their age-related decline in lung function ("lung age") increase smoking cessation rates?
Design: randomised controlled trial.
Allocation: concealed.
Blinding: blinded (outcome assessors).
Follow-up period: 12 months.
Setting: 5 general practices in Hertfordshire, UK.
Patients:
561 current smokers 
35 years of age (mean age 53 y, 54% women, mean 17 cigarettes/d, mean 33 pack-y of smoking). Patients receiving oxygen or with a history of lung cancer, tuberculosis, asbestosis, silicosis, bronchiectasis, or pneumonectomy were excluded.
Intervention:
all patients had spirometry at baseline to measure forced expiratory volume at 1 second (FEV1). Patients in the intervention group (n = 280) were immediately given their results verbally and graphically as "lung age" (the age of the average healthy person who has an FEV1 equal to that of the patient); patients in the control
