Optimisation of services to prevent dental caries for school-aged children in China: a discrete choice experiment.
Article in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesThe objective of this study is to analyse the preferences of guardians of school-aged children for children's caries prevention services (CPS) and their willingness to pay (WTP) for different levels of attributes.
designFour key attributes were identified through a literature review and expert consultations: preventive service time, preventive effectiveness, distance (driving time to service institution) and service cost (out-of-pocket for CPS). A D-efficient design was used to create a discrete choice experiment questionnaire, and data were collected via face-to-face interviews.
settingData collection was conducted between July 2021 and January 2022 in Anhui, China.
participantsGuardians (785) of children aged 3-12 years participated.
main outcome measuresA mixed-logit model was used to estimate preferences and WTP for different attribute levels, and the preference heterogeneity was assessed using a latent class logit model.
resultsPreventive effectiveness was the most important attribute, followed by service cost, preventive service time and distance. Guardians preferred CPS with over 90% preventive effectiveness, a distance of 10-25 min, services offered during vacations and lower service cost. Guardians were willing to pay 409 Chinese yuan (CNY) for higher effectiveness, 84 CNY for shorter distances and 87 CNY for services offered during vacation. Guardians with a college education or higher and females prioritise preventive effectiveness, while guardians who had children with a caries history and who had children with better oral health status preferred CPS during vacation.
conclusionsAll four attributes influenced guardians' preferences for CPS, with preventive effectiveness being the most important. Guardians were willing to pay extra money for better CPS, and preferences varied according to individual characteristics. These findings provide a reference for policy-makers to provide personalised, demand-based CPS.
