Correlation (left column) and Bland-Altman analysis (middle column) between dynamic CT and whole-lung CT means of eight variables studied. Black dotted line is the identity line in the correlation graphs and the line of no difference in the Bland-Altman analysis. Mean difference is represented by dashed line with solid lines representing 95% limits of agreement in the Bland-Altman analysis. The greatest effect on the discrepancy between dynamic CT and whole-lung values was noted between inspiration (filled circles) and expiration (empty circles): thus, these points are highlighted separately. Right-hand column provides density distributions for the discrepancies, again separated by inspiration (solid line) and expiration (dashed line). In all eight variables, inspiration moves the distribution closer to the line of no difference
