Lung weight. Individual changes in lung weight across the entire study period. Straight lines are used to connect individual points (not to suggest that changes occurred linearly over time). Initial lung weights were measured by quantitative analysis of lung CT obtained at baseline; final lung weights were measured on a balance following autopsy. *P = 0.01 (Student's paired t test). CT, computed tomography.
