1 · What the graph read from 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.

2 · The registry

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

objectiveTo explore how the public and dental professionals would value an orthodontic service for adults by eliciting their willingness-to-pay (WTP), a standardised health economics technique which quantifies 'strength of preference' in monetary terms. Despite increasing demand, adults in the UK are only eligible for NHS orthodontic treatment if there is severe dental health or complex multidisciplinary need. Orthodontic services are provided to children aged under 18 years who are eligible by their Index of Orthodontic Treatment Need (IOTN) score. Consequently, many adults who may have a need for treatment as determined by IOTN are unable to access this service.

designCross-sectional survey.

settingGeneral dental practices in North East England and national specialists approached through the British Orthodontic Society (BOS).

participantsPublic participants were recruited from general dental practices. Dentists were recruited from local dental lists and members of the BOS.

methodsParticipants were asked if they would be willing to pay to see an orthodontic service extended to all adults in England with a qualifying IOTN. Clinical photographs of three malocclusions were presented and maximum WTP in additional tax per household per year was elicited using shuffled payment cards.

resultsA total of 205 dentists and 206 public participants were recruited. Pairwise tests showed a statistically significant difference in WTP between the public and professionals for all malocclusions, with the public giving higher valuations. In both groups, the Class III scenario elicited a higher WTP than the class I or II malocclusion. However, when all other factors were controlled for using a regression analysis, the group (public or profession) and the other variables did not significantly influence WTP.

conclusionThe public and professionals were willing to pay for an adult orthodontic service. Due to this variability and unpredictability the allocation of healthcare resources will remain contentious.
