BpTRUth: Do automated blood pressure monitors outperform mercury?

Manual measurement of blood pressure (BP) in the office (MOBP) is inferior in accuracy when compared with ambulatory BP measurements (ABPM) since it misses white coat and masked effects on BP. BpTRU, an automated office BP device (AOBP), has been reported to reduce white coat effect. We performed a retrospective review of the diagnostic accuracy of MOBP (taken by a trained nurse in clinical hypertension) and AOBP using the Bland-Altman method in...
