The progression was larger and statistically more significant in quitters (p\<0.001).Conclusion CALIPER texture analysis provides an objective measure comparable to traditional density/histogram features to assess the lung parenchymal changes in relation to different smoking habits.CALIPER texture analysis provides an objective measure comparable to traditional density/histogram features to assess the lung parenchymal changes in relation to different smoking habits https://bit.ly/3tiIF9a}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/60/4/2102618}, eprint = {//www.qdcxjkg.com/content/60/4/2102618.full.pdf}, journal = {European Respiratory Journal} }
