1 · What the graph read from it

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.

2 · The registry

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

backgroundThe adoption of restrictive diets without medical indication is increasing, but the cognitive factors associated with this dietary behavior remain insufficiently understood. The aim of this study was to examine the proportion of participants following restrictive diets in a self-selected online sample of adults living in Romania and to analyze the associations of nutrition knowledge, beliefs regarding the relationship between diet and health, food vigilance, and social media use with the adoption of restrictive diets without medical indication.

methodsThis cross-sectional observational study was conducted online in a self-selected sample of 766 adults living in Romania. Participants were classified into three groups: no restrictive diet, medically indicated restrictive diet, and restrictive diet without medical indication. Three composite scores were constructed: Restrictive Health Beliefs, Food Vigilance, and Nutrition Knowledge. Differences between groups were assessed using non-parametric tests and χ

resultsAmong the participants, 30.9% reported following a restrictive diet, and 13.1% adopted one without medical indication. Participants who followed restrictive diets scored higher for Restrictive Health Beliefs and Food Vigilance but not Nutrition Knowledge. In the multivariate analysis, Restrictive Health Beliefs showed the strongest independent association with restrictive diets without medical indication. Food Vigilance was only associated with medically indicated restrictive diets (

conclusionsThe results suggest that the adoption of restrictive diets without medical indication is more closely associated with beliefs regarding the relationship between diet and health than with the level of nutrition knowledge. These findings support the development of nutrition education interventions that, in addition to conveying evidence-based information, promote the development of critical thinking and the correction of insufficiently scientifically substantiated dietary beliefs.
