1 · What the graph read from it

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.

2 · The registry

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

Universal access to influenza vaccination in pediatric age is crucial to reducing the burden of influenza among children. This study aimed to assess whether school-based influenza vaccination programs improve access and equity compared to health center-based campaigns, by comparing coverages by parental origin and economic status. We performed an observational, cross-sectional, population-based study in the Region of Murcia, Spain, using data from the regional registry of vaccinations (VACUSAN). Participants were 2018 and 2019-borns vaccinated with live attenuated influenza vaccine (LAIV) during the 2022-2023 health center-based vaccination campaign, and 2019 and 2020-borns vaccinated during the 2023-2024 school-based campaign as well as children born in 2021 before October 9, vaccinated during the 2023-2024 campaign at health centers. The outcome measure was vaccination coverage for each campaign and birth cohort by main parent's origin and economic section. During the 2022-2023 campaign 11,122 3 and 4-year-old children were vaccinated and 16,870 during the 2023-2024 school-based campaign; an additional 4605 2-year-old children were vaccinated at health centers in 2023-2024 campaign. Global coverage rose for 3 and 4-year-olds between campaigns for all main parent's origin and economic sections, with the biggest rise for the Western Mediterranean Origin. Similar results were observed for economic section F003 (foreign children without residence permit). During 2023-2024 campaign, 3 and 4-year-olds, vaccinated at school, achieved higher coverages than 2-year-olds, vaccinated at health centers, with the biggest differences for section 001 (lowest income). School vaccination campaigns achieve higher coverage than health center-based campaigns, particularly among children from disadvantaged socioeconomic groups, thereby promoting equity.
