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 AND
objectiveAn unhealthy diet is one of the most important behavioral factors associated with the risk of progression of prediabetes to diabetes. The present study aimed to determine the effect of an educational program on WhatsApp based on the Theory of Planned Behavior (TPB) on the dietary behaviors of women with prediabetes.
methodsA quasi-experimental study with a control group was conducted on 72 women with prediabetes referring to health centers in Mashhad, Iran. The samples were randomly assigned to two experimental and control groups. Participants in the experimental group received an 8-session educational program based on TPB via WhatsApp. Data were collected using a demographic information questionnaire and a questionnaire based on TPB constructs before, immediately after the intervention and at 3-month follow-up. Data analysis was performed using SPSS version 25 software, with a significance level of p < 0.05.
findingsThe mean scores of attitude, subjective norms, perceived behavioral control, intention, and dietary behavior in the experimental group significantly differed from the control group from baseline to follow-up. (P < 0.001). However, these changes were not significant in the control group.
conclusionThe results suggest that TPB-based nutrition education via WhatsApp can promote dietary behaviors in women with prediabetes. TPB is a suitable theoretical framework for healthy behaviors and can be used to design educational interventions via social media platforms to empower patients with prediabetes.
