Article in BMJ open, 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
purposeAs a historical register-based birth cohort, the
participantsThe cohort includes all newborns in FINDINGS TO DATE: The cohort includes 2 023 613 children with a maximum follow-up of 18 years. This results in 17 752 995 person-years at risk and 3410 cases of childhood cancer. Maternal linkage was possible for 78.3% of children. The vaccination coverage for both nationally recommended and other vaccines was assessed in the cohort. By age 30 months, 38.9% of children received all recommended vaccines, 52.4% received incomplete vaccinations and 8.8% remained unvaccinated. Regarding further characteristics, 57.6% of children were from families with higher education, 20.3% were hospitalised due to a severe infection during follow-up and 74.5% received at least one antibiotic prescription. FUTURE PLANS: While our first study with this historical cohort is dedicated to the question of whether immunity to childhood infections that are covered by the recommended baseline vaccination scheme reduces the risk of childhood cancer, the cohort will offer further opportunities. This includes the evaluation of additional factors potentially influencing the risk of cancer and other diseases in childhood, as well as an extension of the inclusion period beyond 2018 to also include children born during the COVID-19 pandemic.
