Do Perceived Message Effectiveness Ratings Change in Response to Repeated Message Exposures?
Trial report in Health communication, 2025. 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
Perceived message effectiveness (PME) is used in message pre-testing and as an indicator of campaign receptivity. Studies have yet to examine whether PME changes in response to repeated exposures to messages and whether the pattern of change differs for effects perceptions (i.e., perceived impact of messages on intended outcomes) versus message perceptions (i.e., judgments of a message's ability to foster message processing). To address these gaps, we conducted a 3-week randomized clinical trial (RCT) with parallel assignment among 1,514 US adolescents aged 13-17 years who were susceptible to vaping or used e-cigarettes in the past 30 days. Repeated exposures to vaping prevention video ads over time increased both effects perceptions (
