We evaluated the ability of a photoplethysmography-based cuffless BP device, with the intended use of 24-hour ABPM, to estimate nocturnal BP compared to a cuff-based oscillometric device.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Participants underwent 24-hour ABPM with the cuffless device placed on the non-dominant upper arm and a validated cuff-based oscillometric device on the dominant arm. The difference between mean awake and asleep BP (awake-asleep BP change) was calculated for both devices and used in the analyses. The statistical analyses were guided by the Awake\/Asleep test (European Society of Hypertension 2023 Recommendations); however, there were methodological deviances from these recommendations. Most importantly, we used only cuffless BP values that were obtained simultaneously with the reference device.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Data from 50 participants, aged 18-80 years, with mean (SD) inclusion office SBP\/DBP 120.1 (11.5)\/75.3 (7.9), were analyzed. The cuffless device achieved a mean difference [95% limits of agreement] of 1.6 [\u22128.0, 11.2] mm\u00a0Hg for SBP and 1.2 [\u22126.7, 9.1] mm\u00a0Hg for DBP in awake-asleep BP changes compared to the reference. Pearson correlation coefficients (95% CI) for SBP\/DBP were 0.75 (0.59, 0.85)\/0.74 (0.58, 0.84).
