Figure 7

Average values of the parameters of (a-c) oximetry, (d-f) velocimetry and g) aortic PWV. Error bars represent standard error: single asterisks refer to the mean difference in parameters between OHC and YH: upslope (p < 0.005), OS (p = 0.016) and PWV (p < 0.001). Similarly, double asterisks refer to the mean difference in parameters between OHC and PAD: all p < 0.0001 except for OS (p < 0.001) and PWV (p < 0.005).
