Prevalence of Vaccine-Covered and Non-Covered HPV Genotypes Among Unvaccinated Women in Ankara: A Single-Center Study.
Article in Vaccines, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
BACKGROUND/
objectivesUnderstanding the regional distribution of human papillomavirus (HPV) genotypes is essential for guiding effective vaccination and screening strategies. This study aimed to assess the prevalence and distribution of HPV genotypes among unvaccinated women aged 30 years and older undergoing routine screening in Ankara. It also aimed to compare the frequencies of genotypes included and not included in current vaccines and to investigate their association with cervical smear cytology.
methodsThis descriptive, cross-sectional, single-center study was conducted at Ankara Etlik City Hospital between 15 November 2024 and 15 February 2025. A total of 500 sexually active, unvaccinated women aged 30 years or older were enrolled. Cervical swab samples were analyzed for HPV DNA and genotypes using real-time PCR (28-type panel), and cytology results were retrospectively obtained from medical records.
resultsHPV infection was detected in 18.2% of participants. Among HPV-positive women, 71.4% had single-type and 28.6% had multiple-type infections. The most common high-risk genotypes among HPV-positive individuals were HPV 16 (13.2%), HPV 18 (13.2%), and HPV 59 (13.2%). While 35.2% of HPV-positive cases included genotypes covered by the nonavalent vaccine, 64.8% involved at least one genotype not covered, mainly HPV 59, 44, and 51. HPV was detected in 17% of individuals with normal cytology, 19% of those with atypical squamous cells of undetermined significance (ASC-US), and 100% of cases with low-grade squamous intraepithelial lesion (LSIL) (
conclusionsThe findings emphasize the persistence of high-risk and non-vaccine-covered HPV types in the population, highlighting the need for updated vaccination policies and the development of broader-spectrum vaccines aligned with local genotype profiles.
