Blood pressure control rates among hypertensive patients managed in community health centres in Shenzhen, China: a megacity population-based observational study.
Observational study in BMJ open, 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 represents a major public health challenge globally, with a rising prevalence in China. This study aims to explore the factors shaping blood pressure (BP) control among hypertensive patients managed in community health centres (CHCs), with a particular emphasis on the association with age.
methodsThis was a population-based, observational study that used healthcare records from CHC in Shenzhen, covering the period from 1 January 2000 to 8 October 2024. Univariate and multivariate logistic regression analyses were employed to assess the independent associations of various factors with BP control rate. Additionally, the study evaluated the relationship between age and BP control across six distinct age subgroups.
resultsThe study included 1 073 914 participants who met the eligibility criteria, with 955 415 (88.97%) patients achieving BP control. The median baseline age was 55.9 (IQR 18-109) years. Individuals aged 45 years and above demonstrated better BP control rates (46-55, OR 1.053, 95% CI 1.020 to 1.087; 56-65, OR 1.246, 95% CI 1.205 to 1.289; 66-75, OR 2.183, 95% CI 2.103 to 2.265; >75, OR 2.159, 95% CI 2.060 to 2.262). Among young adults aged 18-35 years, increasing age was consistently associated with poorer BP control across most subgroups. For the middle-aged groups (36-45 and 46-65 years), age had little impact on BP control. In the 66-75 years age range, older age was linked to better BP control in some groups.
conclusionThe association between age and BP control varied across age groups. Hypertension management strategies should be tailored to address the unique needs of different age groups, geographical regions and targeted populations.
