Information processes mediate the effect of a health communication intervention on fruit and vegetable consumption.
Trial report in Journal of health communication, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
Health communication interventions have been effective in promoting fruit and vegetable consumption (FVC). To explore mechanisms underlying health communication effectiveness, the authors investigated whether information processes mediated the relationship between health communication and FVC, using data from NC STRIDES. NC STRIDES tested the efficacy of two health communication strategies to promote FVC among a diverse population-based sample of older adults. Participants were randomized to 1 of 4 groups: control, tailored print communication (TPC), telephone motivational interviewing (TMI), or combined (TPC + TMI). To analyze data from 469 participants, the authors constructed multi-sample structural equation models. Information processes mediated the effect of TMI and TPC + TMI on FVC. TMI had an indirect effect on FVC through relevance of the communications. TPC + TMI influenced FVC through perceived relevance of the communications, trust in the communications, and dose recall via two paths. In the first path, relevance was associated with trust. Trust was associated with recall, and greater recall predicted FVC. In the second path, relevance was associated with dose recall, and more recall predicted FVC. Thus, the authors found that key information processes mediated the relationship between a health communication intervention and FVC. Further research should investigate ways to enhance relevance, trust, and recall during the delivery of interventions.
