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
Background: Depressive symptoms affect eating behavior and body mass index (BMI). We investigated their relationship in a non-clinical cohort without depressive or eating disorders and explored whether trait eating behavior mediates the association between depressive symptoms and BMI. Methods: Seventy-seven participants (62.3% women, aged 20-69 years) from the Obese Taste Bud study, with varying weight status and no depressive or eating disorders, completed the General Depression Scale (GDS), Three-Factor Eating Questionnaire (TFEQ), and Food Craving Questionnaire. Multiple linear regression analyses were conducted to examine the associations of depressive symptoms with trait eating behavior and BMI. Mediation analyses were performed using Hayes' PROCESS macro in the Statistical Package for Social Sciences (SPSS). Results: Higher depressive symptom scores predicted greater trait disinhibition ( Conclusion: In non-clinical cohorts, depressive symptoms that do not meet the criteria for depressive disorders meaningfully influence stable patterns of unfavorable eating behaviors and body weight. Trait disinhibition was identified as a mediator linking depressive symptoms and BMI, highlighting a potential behavioral mechanism through which depressive symptoms may contribute to obesity.
