Effect estimate: r = 0.88-0.99
p-value: p=<0.0001
The new oscillometric device provides a simple, non-invasive, and highly reproducible method for measuring pulse wave velocity and arterial stiffness in clinical and epidemiological settings.
Naidu et al. (2005) conducted a cross-sectional in Coronary Artery Disease and Healthy Controls (n=44). PeriScope oscillometric device vs. Inter-observer and inter-period comparisons was evaluated on Inter-observer and inter-period reproducibility of pulse wave velocity measurements (r = 0.88-0.99, p=<0.0001). The PeriScope oscillometric device demonstrated high inter-observer and inter-period reproducibility for measuring pulse wave velocity, with correlation coefficients ranging from 0.71 to 0.99 (p<0.0001).
