(Sero)prevalence of (re)emerging major arbovirus infections in Africa: a systematic review and meta-analysis protocol.
Article in Systematic reviews, 2026. 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
backgroundArbovirus infection outbreaks are becoming more widely reported in Africa. However, it is still difficult and crucial to better understand arbovirus transmission patterns, disease trends, and burdens. The epidemiology of these infections-dengue virus (DENV), Zika virus (ZIKV), chikungunya virus (CHIKV), West Nile virus (WNV), Rift Valley fever virus (RVFV), and yellow fever virus (YFV)-is unfortunately not well understood. This review provides an epidemiological inventory of DENV, ZIKV, CHIKV, WNV, RVFV, and YFV infections in Africa, with helpful results for risk mapping and upcoming prevention and control initiatives.
methodsThis systematic review protocol implements the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and an expert-evaluated design, laboratory assay and reporting evaluation (DARE) concept. Two independent reviewers conducted preliminary literature searches in PubMed in May 2023 to improve search keywords, strategy, and inclusion criteria while considering the context and scientific significance. The final search will be conducted using PubMed, ScienceDirect (SCOPUS), Web of Science Core Collection, African Journal Online, and Google Scholar. Two reviewers will simultaneously and independently conduct searches, screen studies, and extract data. Quality assessment will be performed by two independent epidemiology experts, and discrepancies will be handled by consensus or by consulting a third reviewer. Meta-analysis will be performed to determine the pooled estimate of arboviruses circulation and transmission patterns in Africa. DISCUSSION: With this review, we want to present an epidemiological inventory with information that will be relevant for risk assessment, future arbovirus infection outbreak prevention, and arbovirus infection outbreak control in Africa. This will include estimating the patterns, trends, and burden of arboviral infection across Africa, as well as identifying the regions with the highest risk of transmission. This will be crucial for developing well-informed policies for epidemic prevention. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42023434939.
