Prevalence of dengue virus among febrile patients in urban setting of Bamako, Mali.
Article in IJID regions, 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: We aimed to determine the prevalence of dengue among febrile patients in Bamako and explore its seasonal and demographic variations. Methods: We conducted cross-sectional surveys in July 2021 and February 2022 among febrile patients seeking care at four community health centers in Bamako. Febrile patients were enrolled, and blood samples were tested for dengue using rapid diagnostic tests and polymerase chain reaction. Results: A total of 325 patients were enrolled (175 in July and 150 in February). The overall prevalence of dengue in communes V and VI of Bamako was 16.9%. Females were more represented (66.2%). The median age of the participants was 20 years (interquartile range: 8-30). Adult age (≥18 years) was the only factor significantly associated with an increased risk of dengue infection (odds ratio = 3.2; 95% confidence interval: 1.1-9.4). Conclusions: The prevalence of dengue (16.9%) in communes V and VI suggests that dengue is endemic in Bamako, with a predominance among young adults and females. Adult age was identified as the only significant factor associated with increased risk. Further studies are needed for more insight into the dynamics of dengue transmission and to guide public health actions, particularly those targeting the adult population, to reduce dengue transmission in Bamako.
