Hypertension Among Medical Students in Lubumbashi, Democratic Republic of the Congo: Prevalence, Associated Factors and Comparison of the 2025 ACC/AHA and JNC 7 Classifications.
Article in International journal of hypertension, 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
Background: Hypertension is increasingly recognised among young adults, but its estimated prevalence varies substantially according to the diagnostic criteria used. This study assessed the prevalence and factors associated with hypertension among medical students in Lubumbashi, Democratic Republic of the Congo (DRC), using the 2025 American College of Cardiology/American Heart Association (ACC/AHA) criteria, and compared the findings with the JNC 7 classification. Methods: We conducted a cross-sectional study among students aged ≥ 18 years at the Faculty of Medicine, University of Lubumbashi, from July to August 2023. Blood pressure and anthropometric measurements were obtained using standardised procedures, and sociodemographic, behavioural and family-history data were collected using a structured questionnaire. Hypertension was defined according to the 2025 ACC/AHA criteria and, for sensitivity analysis, according to JNC 7. Factors associated with hypertension were assessed using logistic regression, with adjusted odds ratios (aORs) and 95% confidence intervals (CIs). The agreement between the two classifications was assessed using Cohen's Results: Among 3505 medical students, 1171 (33.4%) were classified as hypertensive according to the 2025 ACC/AHA criteria. In multivariable analysis, hypertension was independently associated with a family history of hypertension (aOR 1.31, 95% CI 1.09-1.59), higher BMI (aOR 1.02 per kg/m Conclusion: Hypertension was highly prevalent among medical students when classified according to the 2025 ACC/AHA criteria, although the prevalence was substantially lower using JNC 7. The limited agreement between the two classifications highlights the considerable impact of diagnostic thresholds on the estimated burden of hypertension among young adults. Early identification of modifiable and familial factors may support targeted cardiovascular risk prevention in university populations.
