Fig. 1

Change in lung clearance index (LCI). Waterfall diagram of the LCI percentage change when comparing duplicate and triplicate measurements (n = 103). No differences in mean absolute changes (modulus) were found between controls (0.9 ± 0.8%), COPD (1.5 ± 0.9%), sarcoidosis (1.1 ± 0.8%) and asthma (1.3 ± 0.7%) in ANOVA (p = 0.1). Solid grey lines indicate mean coefficient of variation (CV) of the respective group with only two datasets marginally exceeding within-test repeatability
