Epidemiological and Entomological Study After the Possible Re-Emergence of Dengue Fever in Croatia, 2024.
Article in Microorganisms, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Autochthonous dengue cases have been continuously recorded in Europe in the past two decades. The first autochthonous dengue case in Croatia was reported in 2010 on the Pelješac Peninsula, while imported cases were recorded continuously thereafter. In 2024, dengue re-emerged in Croatia. An epidemiological and entomological study was conducted after receiving information on dengue virus (DENV) infection in a German tourist probably acquired on Dugi Otok Island in Croatia in May 2024. Serum samples were collected from 30 residents of the Veli Rat region where the patient had stayed. In addition, mosquitoes were collected in the same area. Human samples were tested for the presence of DENV antibodies (ELISA and IFA) and DENV RNA (RT-qPCR), while mosquito samples were tested for DENV RNA (RT-qPCR). DENV IgM or IgG antibodies were found in 8 serum samples, while no one sample was RT-qPCR positive. No cross-reactivity with flaviviruses was detected in seropositive samples, supporting DENV infection. One patient was classified as a confirmed dengue case (IgG seroconversion in paired serum samples) and five as probable cases (IgM detection in a single serum sample). One additional patient, sampled only once, was IgG seropositive. Two of the seropositive individuals reported fever and rash three weeks before testing. The re-emergence of dengue in Croatia highlights the need for continuous monitoring of DENV circulation in both humans and vectors.
