Beyond the Tropics: Clinical Presentation and Epidemiology of Travel-Associated Dengue Fever in a Non-Endemic European Setting.

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
Dengue is a rapidly spreading mosquito-borne viral disease with increasing incidence in Europe, driven by international travel and climate-related expansion of Aedes mosquito habitats. Data on imported dengue in Central Europe remain limited. The aim of this study was to characterize clinical and epidemiological features of imported dengue infections in Austria and identify factors associated with dengue warning signs. A retrospective, single-centre observational study conducted from January 2013 to October 2024. We retrospectively analyzed 175 adults with confirmed travel-associated dengue treated in Vienna, Austria. Demographics, travel history, symptoms, laboratory values, and clinical outcomes were extracted from electronic records. WHO criteria were applied to classify dengue severity. Most infections were acquired in Southeast Asia (72.6%), particularly Thailand. Common symptoms were fever (97.1%), fatigue (97.1%), arthralgia (59.4%), and rash (53.8%). Dengue warning signs were observed in 16% of cases and associated with significantly prolonged leukopenia (
