Comparison of the three quantification methods in terms of relative 99mTc-labeled aerosol distribution (%) during lung ventilation analysis. *p < 0.05 for the indicated lobe, as determined by Welch’s test-based ANOVA. Significant differences between the methods can be seen by viewing the 95% confidence intervals: If two methods do not show overlap of these bars, they differ significantly in relative distribution
