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
objectiveThe study aimed to assess the impact of a game-based nutritional intervention on food consumption, nutritional knowledge and self-efficacy in the adoption of healthy eating practices.
designThis cluster randomised controlled trial included both male and female high school students from private schools in the Federal District, Brazil. Four schools were randomly selected for each group. Investigated variables were age, sex, monthly family income, maternal education level, dietary perceptions and practices, nutritional knowledge and self-efficacy in the adoption of healthy eating practices.
settingIntervention group participants were instructed to play Rango Cards, a digital game developed for the study, on their own, for a period of 7-17 d, while the control group was not provided with any game or material during the study.
participantsThe study included 319 adolescents (mean age = 15·8 (sd 0·7) years).
resultsSignificant reductions were observed in the intervention group compared with the control group for the following variables: habit of eating while watching TV or studying and having meals at fast food restaurants. The intervention group showed increased knowledge of the effects of fruit and vegetable consumption as well as improved self-efficacy in the adoption of healthy eating practices such as reducing Na intake and preparing healthy meals.
conclusionsThe design of Rango Cards is potentially capable of effecting positive changes. Therefore, the digital game promotes autonomy and self-care among adolescents with regard to healthy eating.
