Correction

In this article (BMJ 2023;380:e073488 doi:10.1136/bmj-2022-073488) the authors state “α-blockers such as clonidine and α-methyldopa, which can help with tachycardia caused by the catecholamine surge on standing.” The authors were actually referring to central adrenergic inhibitors such as clonidine and α-methyldopa, so that the corrected sentence reads “Central adrenergic inhibitors such as clonidine and α-methyldopa, which can help with tachycardia caused by the catecholamine surge on standing.” The article infographic has been amended accordingly.
