The impact of culturally-informed messages to reduce sugar-sweetened beverage consumption: An experiment among Black women in the United States.
Trial report in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveSugar-sweetened beverage (i.e., sugary drink) consumption is associated with chronic health issues that disproportionately affect Black women. Culturally-informed (CI) health campaigns may be more effective among Black women than campaigns designed for general audiences. This study assesses the effects of a CI campaign on consumption intentions, comparing these effects to general audience and control campaigns.
methodsWe conducted an online between-persons randomized experiment with a national convenience sample of 502 Black women in February 2023. Participants were randomly assigned to view a CI, general audience, or control campaign. Outcomes were intentions to decrease sugary drink consumption (primary outcome; range 1-7), knowledge of (range 0-4) and perceived susceptibility to health harms (range 1-5) and sharing intentions (range 0-3).
resultsThe CI campaign had significantly higher perceived cultural relevance (M = 4.61) than the general audience (M = 3.64) or control (M = 3.66; p's<0.05) campaigns. Consumption intentions did not differ by campaign condition (F = 0.03, p>0.05). There was no main effect of campaign condition on knowledge or perceived susceptibility (p's>0.05), though findings were moderated by body size. Based on body size, women reported less perceived susceptibility or knowledge when exposed to the CI campaign, compared to either the control or general audience campaign. Sharing intentions did not differ by campaign condition.
conclusionsFuture research should continue to examine the role of refining message content over a longer duration to understand whether the anticipated impact of CI messages can be achieved in the context of sugary drink consumption among Black women.
