Chinese caregivers' preferences and predicted uptake of HPV vaccination: a study protocol for two discrete choice experiments.
Article in BMJ open, 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
introductionHuman papillomavirus (HPV) vaccines have been introduced in the Chinese market since 2016. However, the HPV vaccine coverage is still remarkably low among adolescent girls in China. This study will employ discrete choice experiments (DCEs) to elicit the preferences of Chinese caregivers for HPV vaccine-related profile characteristics and service delivery methods for adolescent girls.
methodsTwo DCEs will be conducted with caregivers of girls aged 9-18 in China. The first DCE will focus on caregivers' preferences regarding the HPV vaccine-related profile for girls aged 9-18, with potential attributes including level of protection against cervical cancer, level of protection against genital warts, risk of severe side effects, number of dose(s), place of manufacture, waiting time and cost for one dose. The second DCE will assess Chinese caregivers' preferences for vaccination service delivery methods, with the potential attributes including source of recommendation, information channel, message framing, how to make an appointment, location for receiving the vaccine and incentives. A total of 300 participants will be recruited to complete the DCEs. We will summarise the key socio-demographic characteristics of participants and use latent class and mixed logit models to assess preferences and preference heterogeneity in HPV vaccination services. ETHICAL AND DISSEMINATION: Ethical approval was obtained from the Research and Ethics Committee at Nanjing Medical University. Findings from this study will be disseminated widely to relevant stakeholders via scheduled meetings, webinars, presentations at conferences and in peer-reviewed journal manuscripts.
