Fig 1. Odds ratios (OR) of the differents emphysema subtypes and lung cancer in the interaction model.

This figure represents the ORs of the different emphysema subtypes with lung cancer. As it is shown, CLE (centrilobular) alone has the highest risk to develop lung cancer which dramatically decreases with the added presence of PSE (paraseptal). Surprisingly, PSE alone is not giving a differential risk of lung cancer.
