Comparison of difference in LCI (LCIN2−LCISF6) to FEV1 (% predicted).

Healthy controls are represented by the open circles and subjects with CF by the solid circles. The difference in LCI was greater as FEV1 became lower such that on average LCIN2 was disproportionately higher than LCISF6 in subjects with abnormal spirometric findings.
