Residual volume/total lung capacity ratio confers limited additive significance to lung clearance index for assessment of adults with bronchiectasisWOS
PloS one, Volume 12, Issue 9, 2017,
LCI is superior to RV/TLC for bronchiectasis assessment. Normalization with RV/TLC is not required. Stratification of LCI and RV/TLC is not associated with significantly different bronchodilator responses.
