Effect of nutritional education based on the precede-proceed model on improving the growth indicators, knowledge, attitude, and food intake of malnourished children: study protocol for a randomized clinical trial.
Article in Trials, 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
backgroundMalnutrition in children is associated with cognitive delays, learning disorders, and disturbances in growth indicators. Inadequate food intake, bad eating habits, lack of nutritional knowledge, low mother's education, and poor economic status are among the causes of malnutrition. School children are more at risk of inappropriate eating behaviors, skipping breakfast, consuming unhealthy snacks, and low physical activity. Therefore, the purpose of this study is to investigate the effect of nutritional education on improving growth indicators, knowledge, attitudes, and food intake.
methodsThis parallel-arm, open-label, randomized clinical trial study will be conducted on 254 children aged 7 to 12 with malnutrition, who will be randomly divided into intervention and control groups. Nutrition education will be conducted during 8 weeks of intervention, and each session will last 45 to 60 min. However, the control group will not receive any education. Weight for age, height for age, BMI for age, food intake, and PRECEDE questionnaire items will be accessed before the intervention, 1 month later, and 3 months after the intervention. The PRECEDE questionnaire prioritizes educational needs and includes specific subscales: predisposing factors (knowledge, attitude, self-efficacy), reinforcing factors, enabling factors, and behavioral assessment. We will analyze the data based on the intention-to-treat protocol. Also, linear regression will be conducted to determine the effect of the intervention on the outcomes after adjustment for the confounding factors. DISCUSSION: Primary school children are at a special age to improve their eating habits, so they are a suitable target for nutrition education interventions to prevent and treat malnutrition. Therefore, the purpose of this research is to determine whether nutrition education can be effective in improving growth indicators and food intake. The results of this intervention can create a new perspective to reduce the prevalence of malnutrition and improve the symptoms caused by it.
