Epidemiological profile of acquired syphilis in children and adolescents in Brazil: a nationwide observational study.
Article in Frontiers in pediatrics, 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
Acquired syphilis, which is historically considered a condition with almost exclusive prevalence in adults, has shown, in recent evidence, an alarming increase amongst the pediatric population. The objective of this study is to analyze and compare the time trends and epidemiological profile of acquired syphilis in the Brazilian population from ages 0 to 19 from 2015 to 2023. It consists of a descriptive, ecological study that utilizes secondary data from the Notifiable Health Conditions Information System (SINAN). The trend analysis used Joinpoint regression to calculate the Annual Percent Change (APC). From 2015 to 2023, 135,699 cases of acquired syphilis were registered in the age group studies, with 78.5% of confirmed cases and a concentration of 94.1% in the 15-19 age group. The results suggest a complex epidemiological scene, with the advancement of syphilis in various groups within the young population, evidencing the urgent necessity to strengthen prevention, diagnosis, and surveillance policies.
