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
backgroundNumerous school-based interventions have used cooking and gardening approaches to improve dietary intake; however, research is limited on the mediation effect of dietary psychosocial factors on the link between the intervention and increased vegetable intake, particularly in children from low-income and racial and ethnic minority US families.
objectiveOur aim was to examine the effects of the Texas Sprouts intervention on dietary psychosocial factors related to intake of vegetables, and whether these psychosocial factors mediate the link between the intervention and increased intake of vegetables in schoolchildren from low-income and racial and ethnic minority US families.
designThis was an analysis of data on secondary outcomes from the Texas Sprouts program, a 1-year school-based gardening, nutrition, and cooking cluster randomized controlled trial consisting of elementary schools that were randomly assigned to either the Texas Sprouts intervention or to control. PARTICIPANTS/
settingParticipants were 2,414 third- through fifth-grade students from low-income and racial and ethnic minority US families from 16 schools (8 intervention and 8 control) in Austin, TX.
interventionThe intervention group received eighteen 60-minute gardening, nutrition, and cooking student lessons in an outdoor teaching garden and 9 monthly parent lessons throughout the academic year.
main outcome measuresChild psychosocial and dietary measures were collected at baseline and post intervention via validated questionnaires. STATISTICAL ANALYSES PERFORMED: Generalized linear mixed models assessed the intervention effects on dietary psychosocial factors. Mediation analyses examined whether these psychosocial factors mediated the link between the intervention and increased child vegetable intake.
resultsChildren in Texas Sprouts, compared with controls, showed significant increases in the mean scores of gardening attitudes, cooking self-efficacy, gardening self-efficacy, nutrition and gardening knowledge, and preferences for fruit and vegetables (all, P < .001). Each of the dietary psychosocial factors mediated the association between the Texas Sprouts intervention and child vegetable intake.
conclusionsBesides targeting dietary behaviors, future school-based interventions should also focus on understanding the mechanisms through which teaching children to cook and garden influence dietary psychosocial factors as mediators of change in healthy eating behaviors.
