Understanding HPV vaccine preferences among sexual minority men living with HIV in Abuja, Nigeria using a discrete choice experiment.
Article in Vaccine, 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
backgroundSexual minority men (SMM) in Nigeria face a disproportionate burden of HPV-related diseases, yet HPV vaccination uptake remains limited due to structural, financial, and sociocultural barriers. Understanding SMM's preferences for vaccination delivery is critical to designing accessible, affirming, and equitable prevention strategies.
methodsA discrete choice experiment (DCE) was conducted with 250 SMM receiving HIV-related care at an affirming clinic in Abuja, Nigeria. Seven attributes were identified through literature review and stakeholder engagement. Participants completed 12 choice tasks comparing hypothetical HPV vaccination scenarios. Hierarchical Bayes estimation was used to derive individual-level utilities and attribute importance scores.
resultsParticipants strongly preferred receiving HPV-related services in SMM-affirming settings and at no cost. Setting type (19.4%) and cost (19.2%) were the most influential attributes, followed by wart prevention (11.4%) and information availability (7.8%). Services described as protecting others from HPV-related outcomes, prevent warts, and require moderate travel (60 min) were moderately preferred. Higher levels of vaccine protection and information availability were less influential in decision-making.
conclusionsPreferences among SMM in Nigeria emphasize the need for free, affirming, and inclusive HPV vaccination services. Addressing structural barriers, especially stigma and cost, will be essential to increasing vaccine uptake. Findings support targeted, community-informed strategies to reduce HPV disparities and promote health equity.
