Oral human papillomavirus infections in Zambian Rural and Urban residents-a community cross-sectional study.
Article in BMC oral health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundHow common it is with the presence of human papillomavirus (HPV) in the healthy and diseased oral cavity is largely unknown for Africans. In this cross-sectional study we assessed the prevalence of oral HPV and the risk factors associated with HPV contraction including sexual practice in the urban and rural Zambian population.
methodsUrban (N = 188) and rural (N = 211) Zambian adults aged 21 years and older living in Ndola and Mansa, respectively, were interviewed about demographical data, oral and coital sexual history and tobacco and alcohol use. Participants were orally examined and underwent a buccal swab test for 12 high-risk HPVs (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, and 59) and two low-risk HPVs (HPV6 and 11) with real-time PCR.
resultsAlcohol consumption was higher in urban participants than rural participants, i.e., 34.1% and 16.6%, respectively, consumed alcohol once a week or more (p = 0.001). Ever-smokers constituted 38.8% of urban and 32.2% of rural participants (p = 0.363). Engaging in orogenital sex was uncommon, however, more common in urban than rural participants (13.3% and 4.3%, respectively, p = 0.003). Only three participants were positive for HPV (HPV16, 35, and 45, respectively).
conclusionsUrban participants displayed higher sexual risk behaviour than rural participants. However, the prevalence of oral HPV infection in Zambia was low, which contrasts to the high incidence of cervical cancer reported for the country.
