Prevalence of Dengue Fever in Nigeria - A Scoping Review.
Article in Journal of global infectious diseases. 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
Introduction: Limited studies have investigated the seroprevalence of dengue viruses (DENVs) in Nigeria. Furthermore, there is no active surveillance program in place. Consequently, this study sought to determine the seroprevalence of DENV in relevant studies published in all six geopolitical zones in Nigeria. Methods: The scoping review was carried out using the Arksey and O'Malley framework. Twelve electronic databases were searched for relevant articles using a predesigned search strategy consisting of Mesh terms and Boolean search operators "AND" "OR." Results: Out of a total of 2646 articles, 21 met the inclusion criteria. The results showed a high prevalence of dengue in Nigeria. The southeast and northwest zones had a prevalence of 70.8% and 64.8%, respectively. There was heterogeneity in the reviewed studies, in which enzyme-linked immunosorbent assay was used in 80%. Two studies used polymerase chain reaction and the detected serotypes were DENV 1 and DENV 2. The use of more than one laboratory method for the detection of DENV showed high sensitivity and specificity. Conclusion: Based on the above findings, it is deduced that dengue is hyperendemic in Nigeria, but there is no uniform data, only a few laboratory-backed seroprevalences are available in some parts of the country. Given this, it is advocated that there is a need for the public health authorities in Nigeria in collaboration with partners to establish a surveillance program to plan prevention and control efforts. It will also give evidence about the need to make vaccines available to especially those at higher risk.
