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
purposeOrthorexia nervosa (ON) is characterized by an excessive preoccupation with healthy eating that may lead to rigidity, distress, and functional impairment. Validated instruments for assessing orthorexic tendencies in adolescent psychiatric settings remain limited. This study aimed to examine the psychometric properties of the Turkish version of the Düsseldorf Orthorexia Scale (TR-DOS) in a clinically referred adolescent sample.
methodsAdolescents aged 12-18 years presenting to a child and adolescent psychiatry outpatient clinic completed the TR-DOS, Orthorexia Nervosa Inventory (ONI), Eating Attitudes Test-26 (EAT-26), and Revised Child Anxiety and Depression Scale-Child Version (RCADS-CV). Psychiatric diagnoses were established through clinician-administered DSM-5 interviews. Construct validity was examined using exploratory and confirmatory factor analyses, internal consistency using Cronbach's alpha and McDonald's omega, and convergent validity through correlations with related measures.
resultsThe sample comprised 209 adolescents (61.2% female; mean age = 15.7 ± 1.72 years). Exploratory factor analysis supported a single-factor solution. Confirmatory factor ana`lysis also supported a one-factor structure, with good model fit (χ
conclusionThe TR-DOS demonstrated satisfactory validity and reliability in a clinically referred Turkish adolescent sample. Level of evidence Level V, descriptive study.
