Incidence and prevalence of acquired brain injury in children and young people globally: A systematic review and meta-analysis protocol.
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
introductionAcquired brain injury refers to any injury or damage to the brain post-birth. It is considered a silent epidemic due to late or missed diagnosis, despite continued interaction with healthcare and longer-term impacts. There is a paucity of robust contemporary evidence that quantifies the population burden of childhood acquired brain injuries. This study aims to estimate the global burden of childhood acquired brain injury by pooling estimates of incidence and prevalence overall, by subtype, and by severity. We will assess variation by time, sociodemographic and clinical characteristics, and geography. METHODS & ANALYSES: MEDLINE, EMBASE, CINAHL, and Scopus publication databases will be searched. Eligible studies will have acquired brain injury incidence or prevalence data on 0-18-year-old individuals within a defined general population-based group from the year 2000 onward. Study design, acquired brain injury and baseline characteristics will be extracted, and quality will be assessed using the JBI Critical Appraisal Checklist. A random effects meta-analysis will be conducted to pool incidence and prevalence. To assess heterogeneity where there is sufficient data availability, subgroup meta-analyses and a meta-regression will be performed by time, age, sex, ethnicity, health/clinical factors, preexisting conditions, socioeconomic factors, country or geographic region. ETHICS & DISSEMINATION: No formal ethics approval is needed due to no primary data collection. Dissemination will be through peer-reviewed publication and contribution to a PhD thesis developing the utility of routinely collected healthcare data to study acquired brain injury. Results will quantify the burden of childhood acquired brain injury by providing a comprehensive synthesis of global data, identifying geographical disparities and data gaps. This review will be beneficial to healthcare professionals and policymakers. Registration with PROSPERO International Prospective Register of Systematic Reviews (CRD420250654936).
