Correlation (Spearman's rho) between CT densitometry and baseline IL-8
| All patients (n = 38) | Excluding tubular bronchiectasis (n = 31) | |
| UZ Perc15 | rs = -0.464 (p = 0.005) | rs = -0.558 (p ≤ 0.001) |
| UZ VI -950HU | rs = 0.447 (p = 0.005) | rs = 0.591 (p ≤ 0.001) |
| LZ Perc15 | rs = -0.447 (p = 0.005) | rs = -0.454 (p = 0.005) |
| LZ VI -950HU | rs = 0.353 (p ≤ 0.02) | rs = 0.401 (p ≤ 0.02) |
UZ = upper zone, LZ = lower zone, VI = voxel index, Perc15 = 15th percentile point, HU = Hounsfield Units.
