1 · What the graph read from it

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.

2 · The registry

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

backgroundAutomated blood pressure (BP) devices may be less accurate in females than males, but this requires further investigation. This study aimed to determine sex differences in automated BP, measured with a single brand and model of device, compared with manual BP, with a focus on cuff sizes and associations with measures of adiposity.

methodsAutomated (Omron HEM-907XL) and manual BP were taken sequentially in a random order among a subsample of participants attending the US National Health and Nutrition Examination Survey, 2017 to 2018. Anthropometry and dual-energy x-ray absorptiometry were used to record body size and composition. Analyses, including multivariable regression to determine sex differences in BP, by cuff size, followed complex survey statistical principles.

resultsA total of 3735 participants (49.0% female [95% CI, 46.4-51.6], 45 years [43-46]) were included. In females, automated systolic BP (SBP) incrementally underestimated manual SBP across larger cuffs up to extra-large (-6.4 mm Hg [-8.0 to -4.9]). In males, automated SBP underestimated manual SBP only with extra-large cuffs (-2.4 mm Hg [95% CI-3.9 to -0.9]). Underestimation by automated SBP with extra-large cuffs was independently associated with all measures of body size indicative of increased adiposity in both females and males. Hypertension classification from automated and manual SBP had moderate agreement for adult/large cuffs (weighted kappa range 0.66-0.79) but weak agreement for extra-large cuffs (0.55-0.58) for females and males.

conclusionsThe automated device used in this study underestimated manual SBP at larger cuff sizes, which was associated with indices of adiposity. Poorer accuracy of automated BP in larger cuff sizes could contribute to inequitable BP-related health care for females and males and requires further investigation.
