Severe dengue-related deaths in the elderly population soared in Southern Brazil in 2024.
Article in IJID regions, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Introduction: Dengue fever is expanding worldwide on the track of climate change. In 2024, more than 14 million cases were reported. Around 6.5 million of those were reported in Brazil alone, reaching a staggering number of around 6000 deaths. Dengue lethality in severe cases were particularly high in Rio Grande do Sul, a historically less affected state which has witnessed an increased incidence and outbreaks in the last 4 years. Design: In this report, we raised some hypotheses to explain the high lethality. Results: Rio Grande do Sul has the highest proportion of elderly individuals among all states in Brazil. This factor, associated with the immunologically naive population, low levels of awareness to detect and treat severe dengue, and the difficulties in managing elderly patients, may have contributed to this higher lethality in severe dengue. Conclusions: The expected increasing dengue incidence in the region in the subsequent years highlights the urgent need of an integrated approach to raise awareness, reduce mosquito populations, and reduce dengue burden in the region, particularly, in the most vulnerable elderly population.
