Integrating Ultrasonographic and Biochemical Markers to Assess Dengue Severity in Critical Care: A Retrospective Study.
Article in Cureus, 2025. 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 and aims Dengue fever can progress to severe disease with hepatic dysfunction and multiorgan involvement. Early identification of markers is essential for timely intervention. This study evaluated transaminitis and gallbladder wall thickness (GBWT) as markers of severe dengue in critically ill patients. Materials and methods A retrospective observational study was conducted on 120 serologically confirmed dengue patients admitted to a tertiary ICU between July and November 2023. Patients were categorized according to the WHO 2009 criteria into dengue with warning signs and severe dengue. Serum transaminase levels and GBWT (>5 mm) were recorded, and their associations with ICU stay, mechanical ventilation, dialysis, and 28-day mortality were analyzed. Results Severe dengue cases demonstrated significantly elevated serum glutamic oxaloacetic transaminase and serum glutamic pyruvic transaminase levels compared with patients presenting with warning signs (p < 0.001). GBWT >5 mm was observed in 75.93% of severe dengue cases versus 54.55% of warning-sign cases (p = 0.015). GBWT >5 mm was significantly associated with an increased need for mechanical ventilation (33.77% vs. 9.30%, p = 0.04), dialysis (23.38% vs. 6.98%, p = 0.025), and higher mortality (25.97% vs. 4.65%, p = 0.003). Conclusion Transaminitis and increased GBWT are simple, cost-effective, and clinically meaningful markers of severe dengue in critically ill patients. Early recognition of these parameters can support timely risk stratification and help guide appropriate ICU management strategies.
