The composite Orthostatic Hypotension Questionnaire (OHQ) score in relation to specific receptor activation. ADRA1 indicates adrenergic α1 receptor; ADRB2, adrenergic β2 receptor; CHRM2, cholinergic muscarinic 2 receptor; OPRL1, opioid receptor‐like 1; and POTS, postural orthostatic tachycardia syndrome.
