Cross-sectional associations between actigraphy-measured sleep and 24-h ambulatory blood pressure phenotypes among self-reported short sleepers with elevated blood pressure.
Article in Sleep medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNocturnal blood pressure (BP) phenotypes predict cardiovascular risk, yet most prior work relies on self-reported sleep rather than actigraphy with ambulatory BP monitoring (ABPM).
objectiveTo test whether actigraphy-measured total sleep time (TST) and sleep efficiency (SE) are associated with nocturnal BP phenotypes in adults with elevated BP and habitual short sleep.
methodsBaseline data from adults with elevated clinic BP and self-reported sleep <7 h/night included approximately seven nights of wrist actigraphy and 24-h ABPM. Linear models estimated continuous outcomes, and Poisson regression estimated prevalence ratios (PRs) for systolic/diastolic non-dipping and asleep hypertension across unadjusted, demographic-adjusted, and fully adjusted models.
resultsLonger TST was associated with a lower prevalence of diastolic non-dipping in unadjusted (PR per 10 min = 0.989, 95 % CI 0.981-0.997) and demographic-adjusted models (PR = 0.991, 95 % CI 0.984-0.997), with attenuation in fully adjusted models. SE was positively associated with systolic dipping in unadjusted models (β = 0.002, p = 0.036) and was nonsignificant after adjustment. Neither TST nor SE predicted asleep hypertension.
conclusionsAmong short-sleeping adults with elevated BP, longer actigraphy-measured TST relates to more favorable nocturnal BP, specifically lower diastolic non-dipping, although effects attenuate with full adjustment. Findings support integrating actigraphy with ABPM to improve characterization of nocturnal BP phenotypes.
