Summary of most relevant inter-group comparisons: a-c) dynamic venous oximetry; d-f) PWV. Data suggest prolonged washout time in smokers (a), reduced rate of re-saturation (upslope) in both smokers and older subjects (b), and similarly, lower overshoot (c). Age-related increased arterial stiffness is evident for all three arterial segments (d-f). Significant p-values (P < 0.05) were highlighted in bold.
