Penile human papilloma virus (HPV) in high risk populations with and without HIV: Epidemiological insights from Argentina.
Article in International journal of STD & AIDS, 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
BackgroundHuman papillomavirus (HPV) is a common sexually transmitted infection, with higher prevalence among men who have sex with men (MSM) and people who self-identify as transgender women (PSTGW). High-risk genotypes (hrHPV) carry oncogenic potential. This study assessed hrHPV prevalence in penile samples from MSM and PSTGW in Buenos Aires, Argentina.MethodsA cross-sectional analysis of baseline data from a longitudinal study was conducted. Participants aged ≥18 were recruited from an HIV prevention center. Penile samples, collected via standardized sandpaper exfoliation, were analyzed using the AmpFire HPV Genotyping Assay for 15 genotypes. Logistic regression models identified factors associated with HPV.ResultsAmong 298 samples from 300 participants (256 MSM, 44 PSTGW), HIV prevalence was 27%. Penile hrHPV prevalence was 31%, with no significant difference between MSM and PSTGW (p = 0.465). Frequent genotypes included HPV-33, HPV-53 and HPV-16 (6.3%, 5.3%, and 4.6% respectively). People with HIV (PWH) showed higher hrHPV prevalence than HIV negative individuals (41% vs 27%, p = 0.023), more infections with ≥3 genotypes (15% vs 4%, p < 0.001), and higher nonavalent vaccine genotype detection (30% vs 15%, p = 0.005). Multivariate analysis associated hrHPV infection with being PWH (aOR = 1.99), >5 sexual partners in the past month (aOR = 1.77), and lifetime sex work (aOR = 2.68).ConclusionsPenile hrHPV was highly prevalent among MSM and PSTGW, particularly among PWH and those with a history of sex work. Low vaccination rate and high prevalence of vaccine-preventable genotypes underscore the need to expand HPV vaccination in these populations.
