High prevalence and atypical genotype distribution of oral human Papillomavirus in an East African HIV cohort: a cross-sectional study.
Article in BMC infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundGlobally, Human Papillomavirus type 16 (HPV-16) is the predominant genotype associated with oropharyngeal cancers. However, little is known about the prevalence and type distribution of Oral Human Papillomavirus (OHPV) in people living with HIV (PLWHIV) in the East African region. The objective of this study was to document the prevalence and circulating genotypes of OHPV infection in a large cohort of PLWHIV attending an urban HIV clinic in Eastern Africa
methodsThis was a cross-sectional study among 1,715 participants of the Makerere University Joint AIDS Program clinic, located in Kampala, Uganda, in East Africa. A salivary sample was collected from which DNA was extracted and subjected to a Polymerase Chain Reaction (PCR) based typing. Data analysis was carried out among participants with complete data (n = 1,243) and relied on descriptive statistics (frequencies, percentages), bivariate testing and multivariate regression modeling, using a conventional p < 0.05 statistical significance threshold.
resultsParticipants had a mean age of 45 (SD = 10) years, and most (69%) were female. An exceptionally high OHPV prevalence of 67% was observed. The non-vaccine, high-risk genotype HPV-45 was the most prevalent type (16%), significantly exceeding the vaccine-targeted types HPV-type 18 (5%) and HPV-16 (2.3%). Most of the HPV-positive samples contained more than one HPV type.
conclusionThis study highlights the high prevalence of OHPV among PLWHIV, with HPV-45 being the most frequently detected type, and smaller frequencies of vaccine-targeted HPV-16 and HPV-18. Our findings highlight the need for continued surveillance and typing of circulating OHPV strains, particularly among PLWHIV, to inform evidence-based preventive strategies.
