Higher Human Papillomavirus Vaccination Coverage Among American Indian and Alaska Native Adolescents and Rural Adolescents in Alaska.
Article in Journal of community health, 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
purposeHuman papillomavirus (HPV) related cancer incidence is higher among American Indian/Alaska Native (AI/AN) women than among White women. Limited access to health care or preventive services in rural communities might increase cancer risk among AI/AN people. To understand disparities in Alaska, this study compares rural/urban HPV vaccination rates of AI/AN with non-AI/AN people.
methodsImmunization rate data were extracted for each year during 2018-2023. Immunization rates from the Alaska Immunization Information System (VacTrAK) were compared between AI/AN and non-AI/AN people.
resultsFrom 2018 to 2023, HPV vaccine series completion among Alaska adolescents aged 13-15 years ranged from 32% to 39%, with 32% up to date in 2023; 48% had initiated vaccination. AI/AN adolescents had significantly higher completion than non-AI/AN peers (48% vs. 29%, p < 0.01), with consistently higher coverage across years and in both rural and urban settings after stratification; rural coverage was higher overall. Regional disparities were substantial, with series completion ranging from 15% to 58%.
conclusionsHPV vaccination coverage among Alaska adolescents remained low from 2018 to 2023, with substantial decline between initiation and series completion. AI/AN adolescents had significantly higher coverage than non-AI/AN peers, challenging assumptions about access and highlighting the effectiveness of community-centered, Tribal-led vaccination efforts. Persistent regional and urban-rural disparities, along with recent declines in AI/AN coverage, underscore the need to strengthen equitable strategies and improve series completion.
