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
backgroundEmerging evidence suggests that discrimination may shape eating-related behaviors through psychosocial pathways. This study aimed to analyze the association between multiple forms of discrimination and disordered eating behaviors among undergraduate students in southern Brazil.
methodsThis cross-sectional study included 1,502 undergraduate students from a public university in Porto Alegre, Brazil. Eating behaviors were assessed using the Adult Eating Behavior Questionnaire, generating food approach and food avoidance scores. Perceived discrimination based on weight, race, gender, and sexual orientation was self-reported and operationalized as both individual exposures and 16 intersectional discrimination strata. Associations were assessed using linear regression models adjusted for age.
resultsThe highest food approach scores were observed among those reporting discrimination based on weight and sexual orientation (β = 9.1; 95% CI: 5.3, 12.8), weight and gender (β = 9.1; 95% CI: 7.0, 11.2), and weight and race (β = 9.0; 95% CI: 5.5, 12.4). For food avoidance, positive associations emerged for discrimination based on sexual orientation and gender (β = 5.2; 95% CI: 3.0, 7.4), while negative associations were found for weight and gender (β = -3.1; 95% CI: -5.0, - 1.2), weight and sexual orientation (β = -3.6; 95% CI: -6.9, - 0.2), and weight alone (β.
conclusionsThese findings demonstrate that perceived discrimination is associated with disordered eating behaviors in distinct and patterned ways, with weight-based discrimination playing a central role. An intersectional approach is essential to capture how multiple, overlapping forms of discrimination intensify vulnerability to disordered eating behaviors.
