Figure 1 (A) Maximum vascular resistance response to orthostatic stress in the two groups and (B) correlation between the maximum vascular resistance response to orthostatic stress and orthostatic tolerance (OT). The maximum vascular resistance response was expressed as percentage change from the supine level. There was a trend for the maximum vascular resistance response to be larger in the group with good orthostatic tolerance, but this was not statistically significant (A). There was a significant positive correlation between the maximum vascular resistance response and orthostatic tolerance (B).
