Global burden and time trends of vaccine-preventable diseases in children and adolescents.
Article in Italian journal of pediatrics, 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
backgroundVaccine-preventable diseases (VPDs) are a major global health concern for children and adolescents. The COVID-19 pandemic further complicated VPDs prevention by halting vaccinations in many areas. This study aimed to analyze the global burden and trends of eight high - burden VPDs in 0 - 19 - year - olds from 1990 to 2021.
methodsUsing data from the Global Burden of Disease 2021 database across 204 countries, incidence and DALYs were stratified by age, sex, and SDI. A linear regression model calculated AAPCs, and a joinpoint regression model identified a significant trend - change years. The SII and CII quantified SDI-related burden inequality.
resultsFrom 1990 to 2021, global VPDs incidence and DALYs decreased. However, in 2021, there were still a large number of cases and DALYs. Hepatitis E DALYs rose, especially in males and infants. Males generally had a higher incidence of most VPDs. Lower SDI regions had heavier burdens, except for varicella and herpes zoster in high-SDI areas. The COVID-19 pandemic increased the incidence of some VPDs.
conclusionsDespite progress in VPDs control, gaps in vaccination, socioeconomic inequalities, and new threats like hepatitis E remain. Targeted actions such as perinatal immunization, hepatitis E vaccination in endemic areas, and restoring pandemic-affected health systems are needed to achieve global health equity.
