Metabolic and cardiovascular comorbidities as predictors of severe dengue in Vietnamese adults: a retrospective study, 2022-2024.
Article in Osong public health and research perspectives, 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
backgroundThis study aimed to determine the prevalence of severe dengue and examine the associations between pre-existing comorbidities and disease severity.
methodsThis retrospective study examined patients with dengue fever who received inpatient treatment at a hospital in northern Vietnam between January 1, 2022, and December 30, 2024. Patients were categorized into 2 groups-severe dengue and non-severe dengue-based on the 2009 World Health Organization criteria. Multivariable logistic regression was performed to assess factors associated with severe dengue.
resultsAmong 3,692 patients, the prevalence of severe dengue was 1.5%. Patients with any pre-existing comorbidity had higher odds of severe dengue compared to those without comorbidities (adjusted odds ratio [aOR], 2.06; 95% confidence interval [CI], 1.20-3.53). Having 2 or more comorbidities was also associated with higher odds of severe dengue (aOR, 2.26; 95% CI, 1.18-4.33). Among individual conditions, hyperlipidemia was associated with severe dengue (aOR, 2.32; 95% CI, 1.17-4.81). Certain combinations of comorbidities, including hypertension with hyperlipidemia (aOR, 2.88; 95% CI, 1.39-5.97), hypertension with cardiac disease (aOR, 4.39; 95% CI, 1.30-14.79), and hyperlipidemia with cardiac disease (aOR, 4.02; 95% CI, 1.19-13.53), were also associated with higher odds of severe dengue.
conclusionPre-existing comorbidities, particularly cardiometabolic conditions, were associated with higher odds of severe dengue. Considering comorbidity profiles at hospital admission may help identify patients who require closer clinical monitoring.
