Statistical analysis
Statistical analyses were performed using STATISTICA 8.0 for
Windows (Statsoft, Tulsa, OK, USA, 1984–2008). A Repeated
Figure 2 Off-line video analysis. Diameters
within the ROI were measured continuously
using the ‘Vasculometer’- edge detection
(Bremser et al., 2012) software and a sampling
frequency of 25Hz.
Figure 3 Signal Processing for FMD analysis. The dark signal depicts
the raw signal of the brachial artery diameter of one subject as measured
with the automated wall detection software. The white line
plots the signal, filtered with a moving average filter (span: 500
frames). The diameter was not recorded during the occlusion. All
measurements were taken with a sampling frequency of 25 Hz.
