10-Year community prevalence and trends of severe asymptomatic hypertension among patients with hypertension in the USA: 2007-2016.
Article in International Journal of Cardiology. Hypertension, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundSevere asymptomatic hypertension (SAH) is associated with significant health cost, morbidity and mortality.
aimEstablish the nationwide prevalence, trends and associated sociodemographic characteristics of SAH among patients with hypertension in the USA.
methodsWe utilized the National Health and Nutrition Examination data collected over five survey cycles (2007-2016). Included were participants aged 20-80 years with self-reported diagnosis of hypertension. SAH was defined as having a mean systolic blood pressure (SBP) ≥180 mmHg and/or mean diastolic blood pressure (DBP) ≥120 mmHg at the time of examination. The Chi square test was used to compare prevalence across different categories. Associations between sociodemographic variables and SAH were assessed using multivariate binary logistic regression.
resultsThe prevalence of SAH among patients with hypertension is 2.15% (95% CI 1.80-2.56), mainly explained by isolated mean SBP≥180 mmHg (86% of all cases), with no statistically significant change between 2007: 2.66% (95% CI 2.10-3.36) and 2016:2.61% [95% CI 1.73-3.94), p-trend = 0.17. Increasing age (OR 1.07, 95% CI 1.04-1.09), NH Blacks (OR 2.20, 95% CI 1.37-3.54), BMI< 25 (OR 2.52, 95% CI 1.48-4.28), lack of health insurance OR 4.92% (95% CI 2.53-9.54) and never married individuals (OR = 2.59%, 95% CI 1.20-5.60) were more likely to have SAH, comparatively. There was no significant association between duration of hypertension and SAH.
conclusionThe prevalence of SAH in the USA is 2.15% and has been stable over the past decade. Our study underscores the importance of identifying barriers to screening and treatment of hypertension which is a major treatable risk factor for cardiovascular disease.
