Validation of the Brazilian version of the Short Inventory of Grazing (SIG).

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
objectiveGrazing is a disturbed eating pattern that has been associated with eating disorders and obesity. One of the new measures to investigate this eating behavior is the Short Inventory of Grazing (SIG), a two-item questionnaire that assesses grazing in general and grazing associated with the feeling of loss of control over eating (LOC grazing). However, the psychometric properties of the SIG have not been assessed in the Brazilian population. The present study aimed to cross-culturally adapt and validate a Brazilian version of the SIG.
methodsThe SIG was adapted to the Brazilian context following international guidelines. Then, 90 undergraduate students completed an online survey including questions from the SIG, the Binge Eating Scale (BES), the Patient Health Questionnaire-9 (PHQ9), the Generalized Anxiety Disorder-7 (GAD7), and a question related to self-reported health status. The internal consistency, test-retest reliability, and convergent validity of the questionnaire were assessed.
resultsThe prevalence rates of at least one weekly episode of grazing in general and LOC grazing were 71.1 and 54.5%, respectively. The internal consistence of the SIG was acceptable (0.81). In addition, SIG scores on both items were positively and significantly associated with BES, GAD7, and PHQ9 scores, and with poorer self-rated health. However, SIG test and retest scores differed significantly.
conclusionOverall, the Brazilian version of the SIG demonstrated adequate psychometric properties. The instrument had adequate internal consistency, with both items exhibiting good convergent validity with related measures.
