Baseline and follow-up Pearson analysis between HRCT indexes (Kurtosis, Skewness, HAA% - 600, HAA% - 700) and functional values (FVC % and DLCO %) in non-progressive fibrosing group. Levels of significance for each correlation are reported in brackets.
a
FVC, forced vital vapacity.
b
DLCO, diffusion capacity of the lungs for carbon monoxide.
c
HAA, high attenuation area.
