Combining patient characteristics and CT measures provided the largest increase in accuracy for the COPD mortality final model (92.3\%, 90.1{\textendash}94.5\%) compared to either other model individually (survey model 87.5\%, 84.3{\textendash}90.6\%; CT model 87.9\%, 84.8{\textendash}91.0\%), but no external validation was performed due to a very low event frequency.Conclusions CT measures of CVD and COPD provides small but reproducible improvements to nodule-based lung cancer risk prediction accuracy from 3 years onwards. Self-reported patient characteristics may not be of added predictive value when CT information is available.Quantitative computed tomography measures of cardiovascular disease and COPD may provide small but reproducible improvements to lung cancer risk prediction accuracy in a screening setting https://bit.ly/3sWyUMM}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/58/3/2003386}, eprint = {//www.qdcxjkg.com/content/58/3/2003386.full.pdf}, journal = {European Respiratory Journal} }
