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

purposeThe Questionnaire on Eating and Weight Patterns-5 (QEWP-5) is a self-report instrument developed to screen individuals for binge eating disorder (BED) and bulimia nervosa (BN) as diagnosed by the DSM-5. This instrument was cross-culturally adapted for the Brazilian Portuguese and well understood by the target sample. The present study aimed to assess the test-retest reliability of the Brazilian version of QEWP-5 in a sample of undergraduate students from Dietitian and Psychology courses.

methodsThe Brazilian version of QEWP-5 was administered to a sample of 345 male and female undergraduate students, from dietitian (n = 179) and psychology (n = 166) courses. The instrument was applied twice with a time interval of 2 weeks between the applications. The kappa coefficient was used to assess the temporal stability of the questionnaire in the screening of BED and BN.

resultsOverall, the kappa coefficient for the screening of BED was .48, and for the screening of BN was .71. In the dietitian course, the temporal stability was .60 (for the assessment of BED) and .80 (for BN). In the psychology course, the kappa values for the assessment of BED and BN were .27 and .60, respectively. All values were statistically significant (p < .001).

conclusionIn general, the stability of the Brazilian version of QEWP-5 was considered moderate to assess BED and substantial for the screening of BN in undergraduate students. Stratifying by course, the questionnaire had higher stability for the assessment of BED and BN in dietitian students. LEVEL OF EVIDENCE: Level V, descriptive study.
