(A) CBF in ml/min of healthy controls and the 3 patient groups during head-up tilt. The left colored column is supine, the dotted column is mid-tilt, and the hatched column is end-tilt. (B) This shows the % decrease from supine for mid and end tilt data in patients and controls. CBF: cerebral blood flow; HC: healthy controls; ME/CFS dOH: ME/CFS patients with delayed orthostatic hypotension; ME/CFS NormHR/BP: ME/CFS patients with a normal heart rate and blood pressure response; ME/CFS POTS: ME/CFS patients with postural orthostatic tachycardia syndrome. Comparison between mid and end tilt data: *=P < .005; **=P < .0005.
