Purpose: To evaluate whether visual CT findings could account for the effect of current smoking. Methods: 500 CT scans were visually evaluated within each lobe. A multivariate model for emphysema index was constructed containing previously described confounders in addition to the visual components associated with smoking status. Results: Current smokers displayed 23% less visual emphysema, 19% more airway wall thickening, and 188% more centrilogular nodule than former smokers (all p < 0.001). The effect of current smoking on the emphysema index decreased after adjustment with confounders and visual parameters. Conclusions: Visual CT findings could partially account for the effect of current smoking.
