Larger lung artery volume tied to deaths in smokers without COPD

Each roughly 25-millilitre increase in artery volume was linked to a death-rate ratio of 1.42 in one cohort and 1.23 in another.Each roughly 25-millilitre increase in artery volume was linked to a death-rate ratio of 1.42 in one cohort and 1.23 in another.
