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

introductionEarlier, we designed and evaluated an educational mass media intervention for improving people's ability to think more critically and to assess the trustworthiness of claims (assertions) about the benefits and harms (effects) of treatments. The overall aims of this follow-up study were to evaluate the impact of our intervention 1 year after it was administered, and to assess retention of learning and behaviour regarding claims about treatments.

methodsWe randomly allocated consenting parents to listen to either the Informed Health Choices podcast (intervention) or typical public service announcements about health issues (control) over 7-10 weeks. Each intervention episode explained how the trustworthiness of treatment claims can be assessed by using relevant key concepts of evidence-informed decision-making. Participants listened to two episodes per week, delivered by research assistants. We evaluated outcomes immediately, and a year after the intervention. Primary outcomes were mean score and the proportion with a score indicating a basic ability to apply the key concepts (> 11 out of 18 correct answers) on a tool measuring people's ability to critically appraise the trustworthiness of treatment claims. Skills decay/retention was estimated by calculating the relative difference between the follow-up and initial results in the intervention group, adjusting for chance. Statistical analyses were performed using R (R Core Team, Vienna, Austria; version 3.4.3).

resultsAfter 1 year, the mean score for parents in the intervention group was 58.9% correct answers, compared to 52.6% in the control (adjusted mean difference of 6.7% (95% CI 3.3% to 10.1%)). In the intervention group, 47.2% of 267 parents had a score indicating a basic ability to assess treatment claims compared to 39.5% of 256 parents in the control (adjusted difference of 9.8% more parents (95% CI 0.9% to 18.9%). These represent relative reductions of 29% in the mean scores and 33% in the proportion of parents with a score indicating a basic ability to assess the trustworthiness of claims about treatment effects.

conclusionsAlthough listening to the Informed Health Choices podcast initially led to a large improvement in the ability of parents to assess claims about the effects of treatments, our findings show that these skills decreased substantially over 1 year. More active practice could address the substantial skills decay observed over 1 year.
