Table 1 Demographic data of ME/CFS patients with a normal HR and BP response (group 1), ME/CFS patients with POTS (group 2), and ME/CFS patients with dOH (group as observed during HUT), all with a significant CBF decrease as measured during HUT

From: Deconditioning does not explain orthostatic intolerance in ME/CFS (myalgic encephalomyelitis/chronic fatigue syndrome)
