Are home blood pressure measurements reproducible and subject to a placebo effect when assessing antihypertensive treatments?
Home blood pressure measurement is highly reproducible and exhibits minimal placebo effect, allowing for smaller sample sizes in trials assessing antihypertensive efficacy.
The results suggest that the HBP measurement is highly reproducible and that there is a minimal, if any, placebo effect. These characteristics of HBP contribute to minimizing the number of subjects necessary for assessment of antihypertensive drug effects in comparative studies between an active treatment and placebo.
