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
objectiveTo analyze the clusters and their social determinants associated with vaccination against human papillomavirus (HPV) in the State of Minas Gerais, Brazil.
methodsEcological study, carried out in 853 municipalities of Minas Gerais, Brazil. The K-means algorithm was used for clustering analysis. The calculation of vaccination coverage (VC) of the HPV vaccine, for males and females, age group 9 to 14 years, between 2014 and 2022, and socioeconomic indicators were considered.
resultsMales had the lowest proportion of municipalities in Minas Gerais achieving the VC target. Of the 5 Clusters generated, Cluster 1 (259 municipalities) showed high urbanization and high VC, but with challenges for male adherence. Cluster 2 (178 municipalities) identified low VC and high poverty, with limited access to health. Cluster 3 (166 municipalities) presented high VC and lower vulnerability, consisting of municipalities with high vaccination uptake and socioeconomic conditions, indicating effective health policies. In Cluster 4 (166 municipalities), public health weaknesses and the need for targeted interventions were identified. Cluster 5 (84 municipalities) presented high urbanization and inequality, but with a large disparity between urbanization and vaccination adherence.
conclusionThus, this study identified that high urbanization, lower vulnerability and greater access to health services are factors that can positively impact vaccine adherence by adolescents.
