Human papillomavirus genotype-specific prevalence and infection risks: a 10-year population-based study from the United States.
Article in Journal of the National Cancer Institute, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundVarious studies have reported on the impact of human papillomavirus (HPV) vaccines. Here we present the largest population-based investigation of genotype-specific distributions over the decade following implementation of the quadrivalent HPV vaccine (HPV-6/11/16/18) in the United States.
methodsLiquid-based cervical cytology samples from individuals aged 15-30 years undergoing cervical screening throughout New Mexico were tested by broad-spectrum HPV genotyping. Weighted relative differences in HPV type-specific prevalence and 95% confidence intervals (CIs) were calculated by comparing individuals screened between 2007 and 2009 (n = 95 915) with individuals screened between 2013 and 2016 (n = 103 371). Weighted logistic regression was used to estimate relative risk of type-specific HPV infections. Tests of significance were 2-sided.
resultsGenotype-specific prevalence fell with statistical signficance for HPV-16 (relative difference = ‒52.6%, 95% CI = ‒56.9 to ‒48.3), HPV-18 (relative difference = ‒62.1%, 95% CI = ‒68.5 to ‒55.8), HPV-31 (relative difference = ‒34.2%, 95% CI = ‒42.1 to ‒26.3), and HPV-33 (relative difference = ‒31.8%, 95% CI = ‒48.4 to ‒15.1). The relative difference increased for other carcinogenic HPV types by 19.5% (95% CI = 14.3 to 24.6) when excluding HPV-16/18. Large reductions in HPV-6/11 relative differences were observed, but overall, noncarcinogenic, nonvaccine types increased. Comparing female individuals born in 1996 with female individuals born in 1989, risk of infection with HPV-6, 11, 16, and 18 decreased by 80.0% among individuals aged 21-25 years. High-grade squamous intraepithelial lesions or worse decreased by 49.4% when extending the evaluation from 2007 to 2018.
conclusionThe incidence of high-grade squamous intraepithelial lesions or worse is decreasing, with large reductions in the prevalence of quadrivalent HPV vaccine types and nonvaccine types HPV-31 and HPV-33, reflecting vaccine cross-protection. Increases in nonvaccine HPV genotypes may attenuate anticipated reductions in HPV-related abnormalities, including cancers, but the benefits of HPV vaccination remain substantial.
