- Agreement of first and second ABI measurement for automated methods. We present concordance correlation coefficients, corresponding confidence intervals, bias between observers, p-value of bias and correlation coefficient between observers.
- VI/VE = Vicorder/Vascular Explorer standard measurements, VI_O/VE_O = Vicorder/Vascular Explorer corrected by observer, VI_E/VE_E = Vicorder/Vascular Explorer corrected by examiner, VE_D = Deflation method of Vascular Explorer.
