Participant selection: Inclusion and exclusion criteria
Criteria used to select participants in the study.
In: resident of Utrech, Netherlands, part of the DOM Cohort, age 50-65 years at baseline, attended screening rounds between 1974 and 1985 in Utrecht
Ex: women diagnosed with breast cancer within one year of recruitment
Comment about participation selection
Strengths: One of the few studies that assessed hypertension and breast cancer risk; lengthy follow up of 19 years (median); anthropometric data measured by trained nurses Limitations: prevalence of hypertension in the study population was high compared to other Netherlands population studies; measurement error could have caused an over estimation of hypertension prevalence

Confounders considered
Other breast cancer risk factors, such as family history, age at first birth, and hormone replacement therapy use, that were taken into account in the study.
Adequately controlled, Confounders: age, BMI, height, parity, familial breast cancer, smoking habits, and OC use
Genetic characterization included
If the study analyzed relationships between environmental factors and inherited genetic variations, this field will be marked “Yes.” “No”, if not.
No

Results Comments
Results do not support an association between breast cancer and hypertension. If there is a link it is likely to be positive and relatively small in size.
