Individual capnographic index (KPIv=[S3/S2]∗100) versus lung clearance index (LCI=cumulative expired volume/functional residual capacity) in n=68/87 CF patients (●) vs. 38/38 controls (○). Vertical line: upper limit of normal of LCI (=7.0). Horizontal line: upper limit of normal of KPIv (=9.3).

5. Fig. 4
Short term reproducibility of the capnographic index (KPIv=[S3/S2]∗100) in controls (n=20/21): mean KPIv of the 1st and the 2nd tests is plotted for each individual against the individual difference between the two tests. The solid line represents the mean difference between the two tests for the group; the broken lines cover two standard deviations above and below this mean difference.
