Human Papillomavirus in the Neovagina of Transgender Women in Thailand: Prevalence, Diversity, and Associated Risk Factors.
Article in Sexually transmitted diseases, 2025. 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
backgroundTransgender women (TGW) face unique sexual health challenges, including neovagina complications, with limited research on sexually transmitted disease prevalence and risk factors. This study aimed to investigate the prevalence, genotype diversity, and associated risk factors of human papillomavirus (HPV) infection in the neovagina of TGW in Thailand. Cisgender women (CGW) are included to provide contextual insights.
methodsWe conducted a cross-sectional study from April to October 2023, recruiting 63 TGW from gender care clinics and community health centers, and 25 CGW from routine gynecological checkups. Samples were collected via Papanicolaou test from the neovagina of TGW and the cervix of CGW for HPV testing. Participants completed questionnaires on sociodemographic characteristics, sexual behaviors, and health-related factors. Univariate Poisson regression was used to explore associations with HPV infection.
resultsAmong TGW, 66.7% had any HPV type, with 41.3% being high-risk and 36.5% having multiple infections. In CGW, 24% had any HPV type and 20% had high-risk HPV. About 34.9% of TGW had 9-valent HPV vaccine-preventable types. Inconsistent condom use and syphilis exposure were associated with a higher risk of any HPV infection (risk ratio [RR] of 1.59 [95% confidence interval {CI}, 1.07-2.35] and RR of 1.57 [95% CI, 1.29-1.90]) and lack of awareness linked to high-risk infection (RR, 1.84 [95% CI, 1.04-3.24]) among TGW. Conversely, CGW showed vaginal and pelvic symptoms as the only risk factor.
conclusionThis novel study of HPV prevalence in TGW neovaginas reveals a high burden of both high- and low-risk types, underscoring the urgent need for tailored prevention, education, vaccination, and screening.
