Association between remnant cholesterol and isolated diastolic hypertension in young adults: a cross-sectional study in China.
Article in BMC cardiovascular disorders, 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
backgroundRemnant cholesterol, the cholesterol content of triglyceride-rich lipoproteins, has emerged as a novel cardiovascular risk factor. However, its relationship with isolated diastolic hypertension, particularly among young adults, remains unclear. This study aimed to investigate the association between remnant cholesterol levels and isolated diastolic hypertension in a population aged under 45 years.
methodsA total of 6,153 participants aged 18–44 years who underwent routine health check-ups at Chinese PLA General Hospital were included after exclusion of secondary or non-isolated hypertension. Participants were categorized into remnant cholesterol tertiles (T1 ≤ 0.6 mmol/L, T2 0.6–0.88 mmol/L, T3 > 0.88 mmol/L). Multiple linear and logistic regression models were used to assess associations between remnant cholesterol and blood pressure levels as well as isolated diastolic hypertension, with progressive adjustment for demographic, metabolic, inflammatory, and renal factors. Restricted cubic spline analysis further examined the dose–response relationship between remnant cholesterol and isolated diastolic hypertension.
resultsHigher remnant cholesterol levels were significantly associated with increased systolic and diastolic blood pressure (both P < 0.001). Compared with the lowest remnant cholesterol tertile, participants with remnant cholesterol > 0.88 mmol/L showed higher odds of isolated diastolic hypertension in both unadjusted and fully adjusted models (OR = 1.73, 95% CI: 1.12–2.68, P = 0.003). Restricted cubic spline analysis revealed a linear positive correlation. Subgroup analyses showed consistent associations across sex, age, body mass index, hyperuricemia, and diabetes status (all P for interaction > 0.05).
conclusionsElevated remnant cholesterol is independently associated with higher blood pressure and greater odds of isolated diastolic hypertension in young adults, suggesting remnant cholesterol may contribute to early diastolic blood pressure elevation.
