Screening for hypertension in a public dental clinic: A single-centre cross-sectional study in Australia.
Article in PloS one, 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
backgroundHypertension affects over 1.3 million people globally and markers of poor oral health have been associated with hypertension.
objectiveThis study aimed to determine hypertension awareness, treatment and control, among adults attending a public dental clinic, and explore age-related differences between younger (< 65 years) and older adults (≥ 65 years) including associations between markers of oral health and hypertension.
methodThis cross-sectional study recruited adults ≥18 years from an Australian public dental clinic between November 2022 and May 2023. Two blood pressure readings were obtained using an automated device and the average used for analyses. Demographic, oral health and medical history details were obtained via survey. Hypertension was defined as a systolic blood pressure (SBP) ≥140 mmHg and/or diastolic blood pressure (DBP) ≥90 mmHg, or being aware (self-reported diagnosis), and treated with anti-hypertensive medication.
resultsParticipants (n = 302) were middle aged (mean 59.9 ± 17.5 years, 51.5% ≥ 65 years, 60.7% female), one third had significant tooth loss (<20 teeth), half required treatment for periodontitis and 52.0% had hypertension (95% CI: 46.2%, 57.7%). Of those with hypertension (n = 157), 82.7% were aware, 76.9% were treated for hypertension, and 56.6% of those treated had controlled blood pressure. Although older adults were more likely than younger adults to have hypertension (74.2% vs 28.1%), younger adults were less likely to be aware and treated (70.7% vs 86.8%, 56.1% vs 86.8%, respectively). Markers of poor oral health were not independently associated with hypertension.
conclusionsIn this population with a high burden of oral disease, hypertension was common highlighting the importance of opportunistic blood pressure assessment. Dental settings may offer an additional point of contact for identifying individuals with undiagnosed or uncontrolled hypertension, particularly among younger adults with lower awareness.
