All the models were adjusted for age at diagnosis (in continuous years), education level (<12 years, 12 years, 13–16 years, 17 years or more), physical activity (measured in total calories per week expended in past year), alcohol consumption (measured in total number drinks over lifetime), smoking (measured in pack-years: never smoke, <10, 10–−<30, 30–<50, >=50), history of hypertension (yes, no), diabetes (yes, no) and body mass index.
