The use of willingness to pay to assess public preferences towards the fortification of foodstuffs with folic acid.
Article in Health expectations : an international journal of public participation in health care and health policy, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
objectivesTo assess public attitudes towards the fortification of flour with folic acid, and quantify their intensity of preference towards the proposed policy.
designStructured interviews describing the proposed policy of fortification followed by questions about the respondent's preferences towards fortification. SETTING AND
participantsA United Kingdom community sample of 76 people interviewed at home. MAIN VARIABLES STUDIED: Direction of preference towards fortification, willingness to pay (WTP) for the preferred course of action, and the reasons behind their preferences.
resultsResponses showed that 51 (67%) were in favour of fortification, 15 (20%) were opposed, while the remaining 10 (13%) were either indifferent or were unsure. Those in favour of fortification tended to be younger and poorer than those opposed to it. Willingness to pay estimates show that those in favour of food fortification had more intense preferences, with mean and median WTP around twice as great. Reasons for being willing to pay were centred on the health benefits, with particular reference being made to the intervention saving lives and it being preventative. Those opposed tended to believe that there was insufficient evidence.
conclusionsThe combination of a policy vote, WTP and qualitative data, allow us to assess the direction, intensity and motivations behind people's preferences. Further work needs to be undertaken to gather more robust estimates of public preferences for fortification, and to better understand attitudes towards public health interventions more generally.
