Prevalence and concordance of penile, anal, and oral human papillomavirus infections among sexually active heterosexual men in Ibadan, Nigeria.
Article in Cancer causes & control : CCC, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundThe data on epidemiology of Human papillomavirus (HPV) infections in men are scarce relative to women generally, particularly among men engaging in heterosexual relationships. This study investigated the prevalence and risk factors for penile, anal, and oral HPV in men in two communities in Ibadan, Nigeria.
methodsThis was a cross-sectional survey involving a face-to-face interview, a clinical examination, and sample collection from participants. HPV genotyping was performed with Anyplex II 28 HPV assay. The prevalences and factors associated with HPV infections using multivariable models and concordance between sites.
resultsOf 316 men, the proportion of any HPV infection in the penile, anal, and oral sites was 40.5%, 9.7%, and 7.8%, respectively. The proportion of any high-risk HPV, low-risk HPV, and multiple HPV infections was highest in the penis followed by the anal and oral sites. Only 5/316 (1.6%) men had concordant HPV in all three sites, with the highest concordance in penile-anal sites relative to penile-oral and anal-oral sites. The odds of penile HPV were higher in men aged 25 years and above. Having penile HPV was associated with higher odds of detecting anal HPV and vice versa. Oral HPV was less likely in men not living with their sexual partners.
conclusionPenile HPV is the most common infection followed by anal HPV and oral HPV infections among heterosexual Nigerian men. Concordant HPV infections was highest in penile-anal sites. Nigerian men, as in other settings, are a reservoir of HPV and it is important to conduct more robust studies to appreciate their role in HPV transmission, epidemiology, and prevention.
