Smoking and atherosclerotic cardiovascular disease in women with lower levels of serum cholesterol

Abstract This cohort study of Koreans examines the relationship between smoking on atherosclerotic cardiovascular disease (ASCVD) and whether serum levels of total cholesterol modify the impact of smoking on ASCVD.
