Cancer in children and adolescents in the Brazilian Amazon: a population-based study.
Article in Ecancermedicalscience, 2025. 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
Background: Every year, about 400,000 children are diagnosed with cancer around the world, 90% of them in developing countries. In Brazil, it is estimated that 7,900 cases are expected by 2023, making cancer the second leading cause of death in this age group. Therefore, this study is relevant for strengthening health surveillance and developing strategies to combat childhood and adolescent malignant neoplasms. Objective: To describe the profile of cancer incidence and mortality in the child and adolescent population of Belém and Ananindeua between 2010 and 2019. Methods: This is a descriptive study, with a quantitative approach, using data obtained from the Population-Based Cancer Registry (RCBP), referring to cancer incidence and mortality in individuals aged 0-19 residing in Belém and Ananindeua. The following variables were analysed: age, sex, race, morphology and case outcome. The data were organised in Microsoft Excel, using the formula: incidence = (number of new cases/total population) × 100,000. The analyses were descriptive, with emphasis on absolute and relative frequencies. Results: A total of 846 new cases of malignant neoplasms were registered among the population aged 0-19. The most frequent morphology was leukaemia, with 42.31 cases per 100,000 inhabitants, followed by malignant tumours of the central nervous system, with 17.92, lymphomas, with 15.82 and bone tumours, with 12.27. The incidence is higher among males, with a large number of cases occurring in the age group 15-19. As for the outcome, 66.1% had no information on the patient's vital status, 29.6% had a confirmed death and only 4.4% had a vital status of alive. Conclusion: The epidemiological data on childhood and adolescent malignant neoplasms in Belém and Ananindeua was detailed, providing more information on the subject. However, it was difficult to obtain some information from the RCBP system.
