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
backgroundObesity and overweight are widespread among individuals in both developed and emerging nations. Obesity is a global health issue, and its prevalence has been increasing in Egypt for several decades. The health belief model (HBM) is a comprehensive framework model that has an important role in preventing disease and promoting health.
objectivesThis study aims to measure the prevalence of overweight and obesity among medical students in the faculty of medicine at Ain Shams University and to determine the effect of nutritional educational program on body mass index and health belief model scales among them.
methodsThis study was conducted in the Faculty of Medicine at Ain Shams University among medical students in 2 phases: phase 1, a descriptive cross-sectional study to calculate the prevalence of the disease; and phase 2, an intervention study that included a sample of 100 medical students whose body mass index was greater than or equal to 25. The study tool is a self-administered questionnaire based on the health belief model for weight control behavior that is tested by the participants before and after the intervention program.
resultsMost participants had a normal BMI, while 40% were overweight or obese. There was a statistically significant difference in the HBM scores before and after the intervention sessions. The mean BMI before the intervention was 29 ± 0.25 and had improved after the intervention session to 29, where there was a highly statistically significant difference (p-value < 0. 001).
conclusionsNutritional education sessions based on the health belief model help in improving the knowledge and habits of high-risk medical students for weight gain. There were substantial changes between before and after the nutrition program interventions.
