Measurement of blood pressure for the diagnosis and management of hypertension in different ethnic groups: one size fits all

551 adults (aged 40-75 years) with and without a previous diagnosis of hypertension, recruited from 28 primary care practices in Central England. Ethnicities included 246 White British, 147 South Asian, and 158 African Caribbean.

Clinic blood pressure measurement (using various protocols: Clinic23, Clinic26, ClinicD1R1) and home blood pressure monitoring (twice each morning and evening for 1 week).

Mean daytime ambulatory blood pressure monitoring (ABPM) as the reference standard.

Diagnostic test performance (sensitivity, specificity, likelihood ratios) of clinic and home-monitored BP compared to the reference standard (mean daytime ambulatory BP) for the diagnosis of hypertension or identification of poor control.surrogate
