Key result
A cuff-based device (CuffCBP) showed good agreement with radial tonometry for estimating central systolic blood pressure (mean difference -0.89 mm Hg; ICC 0.977, 95% CI 0.973-0.982).
Why the study?
Does a cuff-based device accurately estimate central blood pressure indices compared to noninvasive radial tonometry in patients with treated hypertension?
Cross-Sectional (n=182)
Does a cuff-based device accurately estimate central blood pressure indices compared to noninvasive radial tonometry in patients with treated hypertension?
Mean Difference: -0.89
A cuff-based device provides central blood pressure estimates that are substantially equivalent to radial tonometry when using standard calibration, offering a simpler method for central BP assessment.

Cuff-based central SBP/DBP/PP estimates agree with tonometry under standard calibration; leaves open need for invasive validation before wider use.
Peng et al. (2016) conducted a cross-sectional in treated hypertension (n=182). Cuff-based device (CuffCBP) vs. Noninvasive radial tonometry (TonCBP) was evaluated on Agreement in central systolic blood pressure (cSBP) (MD -0.89 mm Hg (ICC 0.977), 95% CI 0.973-0.982). A cuff-based device (CuffCBP) showed good agreement with radial tonometry for estimating central systolic blood pressure (mean difference -0.89 mm Hg; ICC 0.977, 95% CI 0.973-0.982).
