Proposed Lung Density Claim for COPD/Asthma Profile
Following this profile is expected to provide long term instrumental precision (coefficient of variation) of bulk lung density of 3%. Consequently, 2 measurements separated by 3 years will detect a 2.8% change per year with a 95% confidence if long term instrumental precision limits detection of change of lung density using CT.
