Re-evaluating cardiovascular risk in systolic-dominant, diastolic-dominant and parallelly-elevated hypertension: insights from northeast rural cardiovascular health study.
Article in Scientific reports, 2024. 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 is a major risk factor for cardiovascular disease (CVD), with a high prevalence in rural northeastern China. This study assesses the cardiovascular risk associated with different blood pressure patterns: systolic dominant, diastolic dominant, and parallel elevation.
methodsWe analyzed data from the Northeast Rural Cardiovascular Health Study (NCRCHS), which included 8,189 participants aged 35 and above. Baseline surveys from 2012 to 2013 and follow-ups in 2015 and 2018 provided a median follow-up of 4.66 years. Participants were categorized into ten subgroups based on systolic and diastolic blood pressure elevations. Kaplan-Meier curves and Cox regression models were used to examine CVD incidence and cardiovascular risk across these groups.
resultsThe incidence of CVD varied significantly among hypertension categories. Patients with grade 1 hypertension had no significant increase in cardiovascular risk at nearly 5 years. Notably, parallel elevations in systolic and diastolic pressures posed the highest cardiovascular risk, while a predominant rise in diastolic pressure alone did not significantly increase risk. This highlights the importance of analyzing blood pressure comprehensively for cardiovascular risk stratification and suggests rethinking treatment strategies for diastolic dominant hypertension.
conclusionsOur findings call for a nuanced approach to cardiovascular risk assessment in hypertension, taking into account distinct patterns of systolic and diastolic blood pressure. The study supports personalized treatment interventions and reinforces current hypertension treatment guidelines. We advocate for prioritizing non-pharmacological management in grade 1 hypertension and further clinical evaluation of treatment thresholds for diastolic dominant hypertension.
