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
Introduction: Diet and lifestyle habits have a direct impact on students' academic performance. Factors such as skipping breakfast, consuming ultra- processed foods, and lack of physical activity can negatively affect school achievement. Objective: To identify the relationship between eating habits and academic performance among high school students at a public school during 2023. Materials and Methods: A cross-sectional study was conducted with 189 students. Sociodemographic variables, eating habits, nutritional status (body mass index and hemoglobin levels), sleep duration, and level of physical activity were assessed. Academic performance was measured using grade point averages and Saber test scores. Descriptive and multivariate statistical analyses were performed. Results: A total of 60.85% of students reported never eating breakfast or doing so less than once a week, with this behavior being more prevalent among those with lower academic performance. Sleeping eight hours per night (aOR = 1.43; 95% CI: 0.62-3.28) and engaging in regular physical activity (aOR = 5.81; 95% CI: 1.05-31.95) were associated with better academic results. No significant differences were found in terms of body mass index, hemoglobin levels, or consumption of vegetables, fruits, cereal grains, proteins, snacks, and sugar-sweetened beverages. Discussion: Various studies have demonstrated that nutrition plays a key role in cognitive development. Conclusion: Healthy lifestyle habits such as regular breakfast consumption, adequate sleep, and physical activity positively influence academic performance. Therefore, it is essential to strengthen school-based strategies that promote a balanced diet and healthy lifestyle to enhance student achievement.
