Dengue Fever:
Article in Sultan Qaboos University medical journal, 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
Objectives: This study aimed to assess the mortality rate and related factors in dengue fever (DF) patients. Additionally, it will outline the clinical and biochemical characteristics and treatments administered to confirmed cases. Methods: This retrospective cross-sectional study included DF patients who presented to Sultan Qaboos University Hospital between January 2022 and July 2023. Data were extracted from the hospital's electronic system into a pre-designed Excel data collection sheet and analysed. Results: The study identified 319 confirmed DF cases with male predominance. The overall mortality rate was 3.8% (n = 12). Mortality was significantly higher among those with ischaemic heart disease (41.7%; n = 5), chronic kidney disease (25%; n = 3) and those on aspirin (25%; n = 3). Patients presenting with fever, headache, arthralgia and body aches, along with multi-organ involvement, exhibited confusion, lower platelet counts, abnormalities in haematocrit and haemoglobin levels, as well as deranged liver and renal function. Backward stepwise multivariate regression analysis showed that the use of antibiotics (odds ratio [OR] = 6.644, 95% confidence interval [CI]: 1.202-36.742; Conclusions: This study identified a mortality rate of 3.8% among patients with DF. Elevated bilirubin levels and antibiotic use during hospitalisation are independent predictors of mortality. Therefore, it is recommended that such patients be closely monitored for potential signs, symptoms and biochemical changes to reduce the risk of mortality.
