Epidemiologic burden, clinical attribution, and implications for immunization strategies of HPV infection among males in Sichuan, China: a large-sample cross-sectional study.
Article in Virology journal, 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
backgroundThis study aimed to explore the prevalence, genotyping, and the complex association between HPV infection and genitourinary disorders in male patients from Sichuan Province, providing a basis for developing targeted HPV prevention strategies.
methodsA cross-sectional study was conducted on 7,534 male patients who attended Sichuan Provincial People's Hospital between July 2020 and July 2023. HPV genotyping was performed using real-time polymerase chain reaction (RT-PCR).
resultsAmong 3,226 HPV-positive male patients, the overall infection rate was 42.8%. Of these, 29.5% were mono-infected, and 13.3% had multiple infections. HPV types 6, 11, 16, 52, and 43 were the most prevalent, with single infections predominating. In terms of vaccine-related multiple infections (bivalent, quadrivalent, and 9-valent HPV vaccines), the highest infection rates occurred in the ≤ 20 and > 60-year groups, while the lowest was seen in the 51-60-year group (P < 0.05). Co-infections between HPV-16, HPV-52, and HPV-59, as well as HPV-6 and HPV-11, were particularly frequent. Among patients diagnosed with warts, balanitis, rash, dermatitis, urethritis, prostatitis, sexually transmitted diseases (STDs), and other conditions, HPV detection rates were 26.2%, 64.1%, 35.0%, 28.9%, 28.7%, 39.3%, 28.0%, and 35.4%, respectively (P < 0.001). Low-risk HPV types 6/11 were predominant in patients with warts (87.6%), while balanitis was more common with single high-risk infections (40.7%).
conclusionThis study developed a three-dimensional model of age, HPV type, and disease risk in male patients in Sichuan, highlighting the high prevalence of HPV infection in this population.
