Burden of asymptomatic malaria among school-aged children: Protocol for a systematic review and meta-analysis.
Article in PloS one, 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
backgroundAsymptomatic malaria infection remains a major challenge for malaria control and elimination efforts, particularly in endemic settings such as Ethiopia. School-aged children are increasingly recognized as a potential reservoir for malaria transmission due to frequent exposure to infection and the development of partial immunity that allows infections to remain clinically silent. However, available evidence on the burden, species distribution, and determinants of asymptomatic malaria in this population is fragmented and inconsistent. This systematic review and meta-analysis aim to synthesize evidence on the prevalence, Plasmodium species distribution, and risk factors of asymptomatic malaria among school-aged children in Ethiopia.
methodsThis protocol was developed in accordance with the PRISMA-P guidelines. A comprehensive literature search will be conducted in electronic databases (PubMed, Scopus, CINAHL, and ScienceDirect) and additional sources, including Google Scholar and African Journals Online. Eligible studies will include observational studies reporting asymptomatic malaria among school-aged children in Ethiopia. Two independent reviewers will conduct study selection, data extraction, and quality assessment using the Joanna Briggs Institute critical appraisal tool for prevalence studies. A random-effects meta-analysis will be performed using R software to estimate the pooled prevalence. Heterogeneity will be assessed using Cochran's Q test and I2 statistics, and subgroup analyses will be conducted by diagnostic method, study area, study design, years of actual data collection, and transmission season during data collection. Where sufficiently comparable adjusted estimates are available, associations between prespecified factors and AMI will also be quantitatively synthesized.
conclusionThe findings will generate comprehensive evidence to support malaria control and elimination strategies in Ethiopia by highlighting the epidemiological importance of school-aged children as a potential reservoir for infection. The results are expected to inform targeted interventions and strengthen school-based malaria surveillance and prevention programs.
