To the Editor: In his letter1 regarding Heeley et al’s article on cardiovascular risk perception and evidence–practice gaps in Australian general practice,2 Radford quotes, “no [automated blood pressure-measuring machines] were accurate enough to ... replac[e] a manual sphygmomanometer”. The citation dates from 1973, when oscillometric blood pressure monitors such as the Omron HEM-907 — distributed by the High Blood Pressure Research Council of Australia (HBPRCA) with support from the Servier Foundation — did not exist. In defence of digital blood pressure devices, a cluster randomised controlled trial conducted in Australian general practice has demonstrated their superiority compared with existing manual devices.3
