Incidence of conditions by duration of the prevalence period – breast cancer cohort. The prevalence period is the observation period used to exclude patients with the condition prior to cancer diagnosis. Hypertension is not shown to avoid compression of the vertical axis. Hypertension rates (/1,000) are as follows: 6 months 343.4; 12 months 239.4; 18 months 222.2; 24 months 211.9; 30 months 203.8; and 36 months 196.3.
