Effects of a methodological infographic on research participants' knowledge, transparency, and trust.
Article in Health psychology : official journal of the Division of Health Psychology, American Psychological Association, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 19 papers, 1 of them a synthesis that pooled 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.
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
objectiveGiven participants' research literacy is essential for clinical trial participation, evidence-based strategies are needed that improve literacy and easily accessed online. We tested whether an infographic letter-that illustrated how dropouts can distort study conclusions-improved participant knowledge about the impact of dropouts relative to a control letter.
methodIn three distinct online samples purposely recruited to assess reproducibility, young ethnically diverse adults were randomized to read an infographic letter or control letter in a hypothetical scenario. Secondary outcomes included participants' perceived transparency of the research organization, perceived value of retention, and perceived trust of the organization. We purposely included two discriminant items, perceived value for the trial outcome and keeping commitments in general, both hypothesized not to change.
resultsAcross samples, ∼20% more infographic participants correctly answered how dropouts affected study conclusions than control participants. For example (Experiment 3), nearly 90% of infographic participants correctly answered versus only two thirds of controls (88.7% vs. 66.7%, absolute percentage difference 22.0%, p < .0001). Infographic participants had substantially higher transparency, perceived value for retention, and trust (Cohen's ds = 0.4-1.0, ps < .0001), yet importantly did not value the study outcome or report keeping commitments more than control participants (Cohen's ds = 0.0-0.1, ps > .10).
conclusionsPromisingly, this transparent, visually powerful methodological infographic improved knowledge and trust. Future trials could embed and experimentally test whether such low-cost online infographics improve not only research literacy, but also trial retention, especially among populations with less initial trust about research.
