MBW indices (S_cond*, LCI) vs. the mFLD ratio in both lung regions.

<p>(A,C) S_cond* (1/L) and (B,D) LCI vs. mFLD ratio in the (A,B) central and (C,D) peripheral region. Data presented for 12 healthy controls 12 CF adults with stable disease (4 had mild (FEV₁ > 80%), 5 had moderate disease (50%1<80%), and 3 had severe disease (FEV₁<50%)). Dotted lines are range of control subjects in study (i.e mean ± 1.96*SD). Individual subjects with similar FEV₁ [%pred] and LCI 2% are identified by +, * and ×.
